Comprehensive Study on Gate Driver for SiC-MOSFETs with Gate Boost

Koji Yamaguchi Kenshiro Katsura Tatsuro Yamada Yukihiko Sato

IEEJ JOURNAL OF INDUSTRY APPLICATIONS 7(3) 218-228 2018年 [査読有り]

This paper presents a high-speed, low loss, and low noise gate driver for silicon-carbide (SiC) MOSFETs. We propose a gate boost circuit to reduce the switching loss and delay time without increasing the switching noise. The proposed gate driver e...

High-Efficiency Floating Bidirectional Power Flow Controller for Next-Generation DC Power Network

Toru Tanaka Yoshinori Takahashi Kenji Natori Yukihiko Sato

IEEJ JOURNAL OF INDUSTRY APPLICATIONS 7(1) 29-34 2018年 [査読有り]

To realize flexible power flow control for DC power networks, we have proposed a bidirectional power flow controller (BPFC) based on a bidirectional buck-boost converter. It is possible to control the power flow by intentionally introducing additi...

Harmonic Loss Reduction in High Speed Motor Drive Systems by Flying Capacitor Multilevel Inverter

Anudari Tumurbaatar Sae Mochidate Koji Yamaguchi Tomohiro Matsuda Yukihiko Sato

2018 INTERNATIONAL POWER ELECTRONICS CONFERENCE (IPEC-NIIGATA 2018 -ECCE ASIA) 1972-1976 2018年 [査読有り]

In AC motor drive, the harmonic components in the output voltage of inverters generate additional iron losses in magnetic cores and additional copper losses in windings of the motor. Particularly in the case of high speed motors, the ripple of the...

Design Consideration of Flying Capacitor Multilevel Inverters Using SiC MOSFETs

Yukihiko Sato Kenji Natori

2018 INTERNATIONAL POWER ELECTRONICS CONFERENCE (IPEC-NIIGATA 2018 -ECCE ASIA) 1860-1865 2018年 [査読有り]

SiC-MOSFETs are expected as promising power switching devices from the view point of high-speed switching and lower on-state resistance. In the multilevel inverters, the number of switching devices in the main current path increases. Thus, lower o...

A Novel Control Approach to Multi-Terminal Power Flow Controller for Next-Generation DC Power Network

Kenji Natori Yuta Nakao Yukihiko Sato

2018 INTERNATIONAL POWER ELECTRONICS CONFERENCE (IPEC-NIIGATA 2018 -ECCE ASIA) 588-592 2018年 [査読有り]

This paper studies a novel control approach to multi-terminal power flow controller (MTPFC) for next-generation DC power network. We have proposed and validated bidirectional power flow controller (BPFC) and MTPFC as promising power flow controlle...
