This paper proposes a new method of starting the hybrid power filter for wind power generation systems with soft starter. In the proposed method, an active filter of the hybrid power filter behaves a resistor for the source current under the starting condition. Thus the inrush phenomena of the passive filter are perfectly suppressed. The basic principle of the proposed starting method is discussed, and then confirmed by digital computer simulation using PSCAD/EMTDC. Simulation results demonstrate that the proposed starting method can overcome the inrush currents for the passive filter, building up the dc voltage of the active filter.

In recent years, consumer induction-heating (IH) cooking appliances have grown increasingly popular because of their easy cleaning, high efficiency, safety, and controllability. IH food cooking system for consumer home use are indispensable to heat various metallic pans, such as aluminum, copper, stainless steel, and iron cast for further diffusing. Furthermore, these appliances have to satisfy the utility AC grid harmonics regulations of IEC61000-3-2. To meet these requirements, this paper proposes a two-stage soft-switching high-frequency inverter with simple PFC function that is suitable for consumer IH cooking appliances. The proposed system comprises a soft-switching chopper based boost PFC converter with passive snubber and phase-shifted PWM controlled ZVZCS high-frequency inverter. In order to satisfy the utility AC grid current harmonic regulations, a simple PFC control technique with discontinuous current mode is introduced. This technique as well as the fundamental operating performances of the proposed IH system is tested. The effectiveness of proposed IH system is substantially proved from a practical point of view on the basis of the experimental results.

Tomokazu Mishima, Eiji Hiraki, Mutsuo Nakaoka

JOURNAL OF POWER ELECTRONICS 10 ( 1 ) 27 - 33 2010年1月

記述言語：英語掲載種別：研究論文（学術雑誌）出版者・発行元：SPRINGER HEIDELBERG

This paper presents a bidirectional DC-DC converter suitable for low-voltage super capacitor-based electric energy storage systems. The DC-DC converter presented here consists of a full-bridge circuit and a current-fed push-pull circuit with a high frequency (HF) transformer-link. In order to reduce the device-conduction losses due to the large current of the super capacitor as well as unnecessary ringing, synchronous rectification is employed in the super capacitor-charging mode. A wide range of voltage regulation between the battery and the super capacitor can be realized by employing a Phase-Shifting (PS) Pulse Width Modulation (PWM) scheme in the full-bridge circuit for the super capacitor charging mode as well as the overlapping PWM scheme of the gate signals to the active power devices in the push-pull circuit for the super capacitor discharging mode. Essential performance of the bidirectional DC-DC converter is demonstrated with simulation and experiment results, and the practical effectiveness of the DC-DC converter is discussed.

記述言語：英語掲載種別：研究論文（国際会議プロシーディングス）出版者・発行元：IEEE

This paper proposes a new half-bridge based inverter for the DC micro-grid. The proposed topology consists of a three-leg inverter, which can be constructed by an intelligent power module (IPM). Using the IPM gives cost-effective inverters for the dc micro-grid. In the proposed half-bridge based topology with a three-leg inverter, two legs are used for two single-phase half-bridge inverters, where the neutral line is grounded. The third leg performs a power de-coupler balancing the mean value of two dc capacitor voltages. This power de-coupler exchanges the energies between two dc capacitors connected to two single-phase half-bridge inverters. Thus the capacity of the dc capacitors of the half-bridge inverters can be dramatically reduced as compared to those of the previously proposed half-bridge inverters for the dc micro-grid. The basic principle of the proposed half-bridge based inverter is discussed in detail, and then confirmed by digital computer simulation using PSIM software. Simulation results demonstrate that the capacity of the dc capacitors is reduced by one fortieth as compared to those of the previously proposed half-bridge based inverter used in the dc micro-grid.

記述言語：英語掲載種別：研究論文（国際会議プロシーディングス）

This paper proposes a new half-bridge inverter based active power quality compensator (APQC) for electrified railways with a three-leg inverter. The first-leg is connected to α-phase, and the second-leg is connected to β-phase. The midpoint of two capacitors on the dc side is connected to the ground line. These two half-bridge inverters exchange the active power on the each feeder each other through two dc capacitors, and compensate the negative-sequence and harmonic components of the load currents. The third-leg performs a dc voltage balancer for two dc capacitors connected to the half-bridge inverters. Thus the balanced and sinusoidal source voltages and currents factor are attained on the primary side of the Scott transformer with the balanced dc capacitor voltages. The basic principle of the proposed half-bridge inverter based APQC is discussed in detail, and then confirmed by digital computer simulation using PSIM software. Simulation results demonstrate that the balanced source currents with the unity power factor are obtained on the primary side the Scott transformer in the traction substation systems balancing two dc capacitor voltages. © 2010 IEEE.

This paper proposes a new current balancer in single-phase three-wire secondary distribution systems using the correlation coefficients. The components of the load currents correlative to the primary side voltage waveform, which correspond to the active currents, are detected in each feeder, then the nonactive and unbalanced-active components are compensated on the source side. The balanced currents with unity power factor are obtained in each feeder. The basic principle of the proposed method is discussed in detail, and then confirmed by digital computer simulation. A prototype experimental system is constructed and tested. Experimental results demonstrate that the balanced source currents with unity power factor are obtained in spite of unbalanced load currents. (C) 2009 Wiley Periodicals, Inc.

This paper proposes a new control method for reducing the capacity of an active power quality compensator with a three-leg inverter used in electrified railways. In the proposed control method, the fundamental reactive and unbalanced-active components of the load currents are detected. The non-active and unbalanced-active components are compensated on the source side with the fundamental reactive power control. This reactive power control reduces the capacity of the three-leg inverter, which performs the active power quality compensator. The basic principle of the proposed control method is discussed in detail, and then confirmed by digital computer simulation using the PSIM software. A reduced-scale experimental model is constructed and tested. Experimental results demonstrate that the balanced sinusoidal source currents with the power factor of 0.9 are obtained, reducing the capacity of the three-leg inverter by 13% as compared to the already proposed control method.

This paper proposes a large-capacity capacitor simulator consisting of a chemical capacitor and three-leg converter. One of three legs performs a bi-directional chopper. The others are used for a PWM rectifier. In the charging mode the most of the power stored in the chemical capacitor is injected to the utility through the PWM rectifier. In the discharging mode the power is supplied to the chemical capacitor side from the utility through the PWM rectifier. Thus the proposed simulator performs a large-capacity capacitor. The basic principle of the proposed simulator is discussed in detail. A prototype experimental model is constructed and tested. Experimental results demonstrate the validity and excellent practicability of the proposed simulator.

記述言語：英語掲載種別：研究論文（学術雑誌）出版者・発行元：WILEY

This paper proposes a novel and simple control method for the active power quality compensators (APQCs) used in electrified railways. The proposed method uses only the constant dc capacitor voltage control block, which is commonly used in the APQCs. No detection blocks of the harmonic, reactive, and negative-sequence components are necessary. Thus we offer the simplest way to compensate the harmonic, reactive, and negative-sequence currents on the primary side of the Scott transformer in the traction substation. The basic principle of the proposed control method is discussed in detail, and then confirmed by digital computer simulation using PSIM software. A prototype experimental model is constructed and tested. Experimental results demonstrate that the balanced source currents with the unity power factor are obtained on the primary side with the proposed control method, which uses only the constant dc capacitor voltage control.

IECON: 2009 35TH ANNUAL CONFERENCE OF IEEE INDUSTRIAL ELECTRONICS, VOLS 1-6 3023 - 3028 2009年

記述言語：英語掲載種別：研究論文（国際会議プロシーディングス）出版者・発行元：IEEE

This paper proposes a constant dc voltage control based strategy for an active power quality compensator (APQC) used in electrified railways. The proposed strategy consists of only an I-PD based constant de capacitor voltage control with an added moving average type low-pass filter (LPF). The added LPF improves the response time of the constant dc capacitor voltage control for the APQC. Thus we offer the simplest control method for the APQC used in electrified railways with the improved response time. The basic principle of the proposed control strategy is discussed in detail, and then confirmed by digital computer simulation using PSIM software. A proto-type experimental model is constructed and tested. Experimental results demonstrate that the balanced source currents with the unity power factor are obtained on the primary side the Scott transformer in the traction substation systems, improving the response time by one-fourth as compared to that of the previously proposed control method.
