Criteria for Using Antiparallel SiC SBDs With SiC MOSFETs for SiC-Based Inverters

Koji Yamaguchi Kenshiro Katsura Tatsuro Yamada Yukihiko Sato

IEEE TRANSACTIONS ON POWER ELECTRONICS 35(1) 619-629 2020年1月

The paper confirms that removing antiparallel silicon carbide (SiC) Schottky barrier diodes (SBDs) from SiC-based inverters offers positive effects without critical impact on inverter loss and electromagnetic interference (EMI) issues, moreover, t...

A Universal Control Method to Realize Plug-and-Play Converters for Microgrids

Hazuki Esashika Kenji Natori Yukihiko Sato

2019 10TH INTERNATIONAL CONFERENCE ON POWER ELECTRONICS AND ECCE ASIA (ICPE 2019 - ECCE ASIA) 481-487 2019年

In recent years, AC and DC microgrids have been extensively studied. By constructing microgrids, it is possible to promote installing renewable energy resources. Most of components (renewable energy sources, storage devices, load, and so on) are c...

High Power Density SiC-Based Inverter with a Power Density of 70 kW/liter or 50 kW/kg

Koji Yamaguchi Kenshiro Katsura Tatsuro Yamada Yukihiko Sato

IEEJ JOURNAL OF INDUSTRY APPLICATIONS 8(4) 694-703 2019年

This paper presents a high power density silicon carbide (SiC)-based inverter, with a two-level voltage-source structure having forced air cooling, which provides a high volumetric power density of 70 kW/liter or 50 kW/kg in gravimetric terms. In ...

Performance Analysis of High Frequency Isolated AC/DC Converter Based on Matrix Converter

Zarchi Linn Koji Shigeuchi Yukihiko Sato

2018 15TH INTERNATIONAL CONFERENCE ON ELECTRICAL ENGINEERING/ELECTRONICS, COMPUTER, TELECOMMUNICATIONS AND INFORMATION TECHNOLOGY (ECTI-CON) 290-293 2018年

This paper describes about a two-stage power conversion system with high frequency isolated AC/DC converter to interface the AC distribution network with the dc load. This system converts the three phase AC power input from the grid to DC power ou...

A New Modulation Method for a Bidirectional Isolated Three-Phase AC/DC Dual-Active-Bridge Converter to Realize Higher Efficiency in Wide Output Voltage Range

Koji Shigeuchi Kensuke Sakuma Jin Xu Noboru Shimosato Yukihiko Sato

2018 IEEE ENERGY CONVERSION CONGRESS AND EXPOSITION (ECCE) 592-598 2018年

This paper presents a new modulation method for a bidirectional isolated three-phase AC/DC Dual-Active-Bridge (DAB) converter to realize higher efficiency in wide output voltage range. The proposed modulation method realize the bidirectional power...
