High Speed dV/dt Control Technology for a SiC Power Module for EV/HEV Inverters Using a Multistage Drive Circuit

Autor: Tetsuya Hayashi, Numakura Keiichiro, Daiki Sato, Taku Shimomura

Publikováno v: 2018 IEEE Energy Conversion Congress and Exposition (ECCE).

This paper presents a simple multistage drive circuit that can reduce turn-off loss by 27% from our previously presented paper for a silicon carbide metal-oxide-semiconductor field-effect transistor (SiC-MOSFET) inverter for EV / HEV traction motor d

High speed dV/dt control technology for SiC power module for EV/HEV inverters

Autor: Takayuki Ikari, Ryusei Yamada, Numakura Keiichiro, Tetsuya Hayashi, Okubo Akinori, Taku Shimomura

Publikováno v: 2017 IEEE Energy Conversion Congress and Exposition (ECCE).

This paper presents dV/dt control technology that enables lower switching loss and surge, especially higher speed switching of silicon carbide (SiC) devices. This technology is a surge reduction method using a high-speed passive gate driver that inde

Influences of Isotropic and Anisotropic Material Properties on Stress Intensity Factors of the Crack Tip under Biaxial Stress

Autor: Akira Shimamoto, Tetsuya Nemoto, Taku Shimomura, Satoru Yoneyama

Publikováno v: Key Engineering Materials. :1598-1603

In order to clarify the effect of anisotropy on local deformation and the stress intensity factors in the vicinity of the crack tip under complicated stress states, biaxial loading tests were carried out on isotropic (Photoelastic sheet: PSM-1, Measu
