| 摘要： | To meet the application requirements, parts of the permanent magnets are not magnetized directly after production. They have to be magnetized afterwards by application of a high external field which can come from a magnetizer. Therefore, in this paper, a method based on the switching power circuit is proposed. In the method, the inverter is first included to generate a basic square voltage. A double-voltage circuit is then utilized to further boost this square voltage. This process is followed by using the modularization design of switching capacitors so that the proposed circuit can provide large magnetizing current to loads with the interleaving mode. To validate the effectiveness of the method, a prototype is set up in the laboratory. The hardware tests with the non-magnetic ferrite magnet and post-assembly Interior Permanent Magnet motors are made. Test results indicate that the proposed circuit can generate the required
magnetizing current indeed. |

| 摘要： | : This paper presents a C-rate control method for a battery/supercapacitor (SC) hybrid
energy storage system (HESS) to enhance the life cycle of the battery in electric vehicles (EVs). The
proposed HESS provides satisfactory power for dynamic movements of EVs (e.g., acceleration or
braking) while keeping the battery current within a secure level to prevent it from degradation.
The configurations of conventional HESSs are often complex due to the two energy storages and
their current/voltage sensing involved. Therefore, in this paper, a simple current-sensing scheme is
utilized and the battery is directly treated as a controlled variable to help the battery output current
remain stable for different load conditions. While the proposed circuit requires only one current
feedback signal, neither the SC nor load current sensors are needed, and the circuit design is thus
significantly simplified. Both simulation and experimental results validated the effectiveness of the
proposed HESS operating in conjunction with the motor drive system. The proposed method aims at
fully utilizing recycled energy and prolonging battery lifespan.

| 摘要： | This paper proposes a control strategy to enhance the operating efficiency of a Hybrid Energy
Storage System (HESS) for an Interior Permanent Magnet Synchronous Motor (IPMSM)
drive. In this method, the battery and super-capacitor (SC) are connected by an interleaved
DC-DC (DD) converter where a bypass DD scheme with the inherent anti-parallel diode of
power switches is used to create another shorter path for battery discharge. In this design, an
adjustable dc-link voltage is accomplished to fit the characterizations in various motor
operating conditions. Then, with the corresponding control design, the proposed HESS can
operate in an optimal state to improve efficiency and extend the battery lifetime. To validate
the effectiveness of the method, several operation scenarios including acceleration, constantspeed
and deceleration of the IPMSM are examined using simulations. This is further
supported through the experimental study. The test results obtained under the buck, boost
and bypass converter scenarios consolidate the feasibility and practicality of the proposed
approach in an attempt for potential electric vehicle applications. |

| 摘要： | Regardless of whether level 1, level 2, or dc fast charging, several methods are under development or available as an aftermarket option for Plug-in electric vehicles (EVs). While confining the charging behavior of EVs to low-load periods is difficult, it leads to significant and uncertain load peaks and valleys in the utility power network. Therefore, this paper proposes a new method for an electric vehicle charger. The proposed charging method involves power supervisory characteristics on the basis of the paradigm of a constant-current and a constant-voltage (CC–CV) charger so that the external commands from the demand-side resource aggregator in the smart grid can be executed. In the method, first, a feedback loop is included in the controller to formulate the relationship between battery voltage and charging power as a quadratic concave downward polynomial. The controlled output power at the beginning of constant voltage charging is then set to the maximum value of the quadratic polynomial because the charging power requirement near this point is closed to the highest. Hence, if the charging power is lower than the allowable maximum power, the proposed charger is determined to have followed the traditional CC–CV charging steps. On contrast, the proposed circuit launches the power control loop when the actual charging power is beyond the maximum power limitation of aggregator. The proposed charger can keep the power consumption inside an allowable range of aggregator. That is the power consumption at the EV charging sites becomes directly programmable by their aggregators. The proposed method is examined by conducting an interactive test of a remote energy management system and the proposed controller. The results revealed that the proposed method provide an easy method to dynamically control consumption pattern of the EV charging for demand-side power management. |

| 摘要： | This paper presents a novel maximum power point tracking (MPPT) method based on the grey wolf optimisation (GWO) technique for photovoltaic (PV) power generation systems. The proposed method utilises previous working duty cycles and their corresponding voltage and current data to compute the instantaneous DC impedance of a PV string. To determine the peak power characteristics of any PV string, the impedance variation of that PV string is used as an efficient shading factor. This shading factor simplifies the calculation of the GWO-MPPT algorithm to obtain multiple peak targets under partial shading conditions. Thus, the efficiency of the proposed power tracking technique can
be improved considerably. The effectiveness of this method was validated through both simulation and hardware implementations. Results revealed that the search performance of five iterations of the proposed method was similar to that of ten iterations of a traditional GWO-MPPT method under normal conditions without shading. These results confirm the practicability of the proposed method in various applications. |

| 摘要： | This paper presents a cumulative current-magnetizing method for magnetization of permanent magnet, aimed at alleviating the bulky capacitor problem of traditional capacitor-discharged impulse magnetizers. The method employs circuit resonance to boost the output voltage. The resonant alternative current (ac) voltage is then directly discharged to the magnetizing coil without using any rectifier. The proposed resonant ac discharge repeats a number of times over several milliseconds. This allows the magnetizing current to increase incrementally until it reaches the peak that is sufficient to fully magnetize the permanent magnet. With this design, the energy for magnetization is accumulated by small steps, and each increment would require much lower energy. This results in smaller capacitors needed compared to traditional designs. To validate the effectiveness of the proposed scheme, several pieces of ferrite magnet without being pre-magnetized were tested using the developed magnetizer. The test results support the feasibility and practicability of the scheme for potential applications. |

| 摘要： | Alternative energy power generation has emerged as a crucial research topic in studies on modern energy
systems. Because of the inherently intermittent generating feature of distributed generation systems, system
operations associated with the integration of distributed generation into existing power networks may suffer
from voltage variations and power delivery problems. Therefore, this paper proposes a new unified power
quality conditioner (UPQC) scheme. The proposed UPQC consists mainly of two back-to-back inverters that
are connected together by a direct current capacitor and installed in series and in parallel with two adjacent
feeders. The UPQC can be operated not only for maintaining a downstream voltage to mitigate upstream voltage sags but also for absorbing real power from one feeder and transferring it to the other feeder. To validate the effectiveness of the proposed scheme, scenarios including voltage sags and power transfer between two feeders were tested through experimental validations. The test results help consolidate the feasibility and practicability of the scheme for potential applications. |

| 摘要： | Conventional dynamic voltage restorers (DVRs) install parallel battery and capacitor
sets at the DC bus to supply the required power for voltage sag compensation.
However, the reactive power output of a DVR may increase the ripple voltage at the
inner DC bus, possibly resulting in a higher operating temperature of the battery and
thus decreased battery life. This paper proposes a DVR system that uses a cascade
power module to effectively compensate voltage sag. By separating the active and
reactive compensation powers, the proposed DVR provides a lower ripple DC link for
extending battery life and offers a flexible way to design the capacitor bank. To
confirm the effectiveness of the proposed design, theoretical analysis and experimental
validation were conducted under various scenarios. Test results confirm the feasibility
and practicality of the proposed method. |

| 摘要： | Comprehension of open-circuitvoltage (OCV) function and battery impedance can be used to evaluate the residual
energy and dynamic voltage response of lithium batteries. However, noise contamination during data sampling may affect the
accuracy of the derived OCV function and battery impedance extraction, resulting in a poor evaluation performance. By
aiming at formulating a more representative circuit-based model, this study proposes a hybrid averaging method along with
an impedance network observation approach that is embedded within a time–frequency localisation method, anticipating
eliminating the influences of sampling noise such that the characterisation of the OCV function and battery impedances can
be better ensured. In such an integrated approach, the trimmed relevance vector regression is also added, which is followed
by two cascaded R–C networks in order to fit the characteristics of battery impedances. Through the method proposed in this
paper, it is found that the average error can be decreased to be less than 20 mV. Both battery residual energy and I–V
performance are more effectively comprehended. |

| 摘要： | This paper presents the circuit and control method for piezo-ceramic drives. With the
proposed method, a gap is imposed in the transformer core to increase the leakage inductance. This
flattens the voltage gain curve of the piezo-ceramic driver over the resonant frequency range, so
voltage gain changes are insensitive to frequency changes. In addition, resonant frequency tracking
and power control methods are developed, while the circuit is capable of zero-voltage soft-switching
such that the circuit operation efficiency can be improved. In order to solidify the practicality of the
circuit design, mathematical analysis and experimental validations have been thoroughly performed.
The test results help to confirm the effectiveness of the proposed method and demonstrate its

Based on the Field-Oriented Control (FOC) signal, the proposed method analyzes the motor-driving voltage spectrum and finds that the second-order harmonic component of motor-driving voltage can be used as an index to quantify the degree of inter-turn short circuit when the interturn short-sircuit fault occurs. This proposed approach has been tested through the theoretical analysis and Matlab/Simulink computer simulation.

| 摘要： | In this paper, based on the paradigm of the cascade inverter technique, a new
approach to control the dynamic voltage restorer will be proposed. In the method, the required
series voltage for the sag correction is first decoupled by the vertical and horizontal component
referred to the phase of load current. The vertical and horizontal voltage component is then
generated and compensated via the different reactive and active power module. In this case, as
the super capacitor-aided reactive power module can output a large amount of the compensation
power, the proposed system will take full advantages of less real power injection during the DVR
operation, mitigating a severe and long duration voltage sag with a significantly smaller energy
demand from the cascaded inverter. The method proposed in this paper will be examined under
various scenarios. The results help consolidate the feasibility and practicability of the approach
for the applications considered. |

| 摘要： | This paper presents a battery/ultra-capacitor (UC) energy storage system for the operation of permanent magnet synchronous motor drives in electric vehicles (EVs). In this system, when the EV is used for accelerated operation, the battery provides a stable voltage to the inverter through the DC-DC converter. At the same time, the battery and UC jointly release energy to the inverter to share the larger current demand of the EV motor. In constant speed operation, the battery supplies energy to the inverter through a shunt diode to avoid additional power losses while the DC-DC converter is operating. During the regenerative braking mode, the current produced by the EV motor is charged to the UC to reduce pulse currents flowing into the battery, which may shorten battery life. To validate the effectiveness of the circuit design, several operation scenarios including buck and boot voltage conversion for the operation of proposed battery/UC ESS were examined in the experimental studies. Test results consolidates the feasibility and practicality of the circuit method for the EV applications. |
