A Gate Drive With Power Over Fiber-Based Isolated Power Supply and Comprehensive Protection Functions for 15-kV SiC MOSFET
TL;DR: In this paper, a 15kV silicon carbide (SiC) MOSFET gate drive is presented, which features high commonmode (CM) noise immunity, small size, light weight, and robust yet flexible protection functions.
Journal ArticleDOI
7-kV 1-MVA SiC-Based Modular Multilevel Converter Prototype for Medium-Voltage Electric Machine Drives
Jianyu Pan,Ziwei Ke,Muneer Al Sabbagh,He Li,Karun Potty,Will Perdikakis,Risha Na,Julia Zhang,Jin Wang,Longya Xu +9 more
TL;DR: This article presents the design and development of a 7-kV dc bus, 1-MVA, 0–1000 Hz modular multilevel converter (MMC) prototype for high speed medium-voltage variable frequency drives and demonstrates the performance of both the SiC-based submodule and the full-scale MMC system.
Proceedings ArticleDOI
Design of a 10 kW GaN-based high power density three-phase inverter
TL;DR: In this paper, a half-bridge structure is designed for a two-level three-phase voltage source inverter to achieve low parasitic inductance and strong cooling capability at the same time.
Journal ArticleDOI

He Li,Xiao Li,Xiaodan Wang,Xintong Lyu,Haiwei Cai,Yazan M. Alsmadi,Liming Liu,Sandeep Bala,Jin Wang +8 more
TL;DR: In this paper, the authors present the short-circuit behavior and degradation of a 650-V/60-A enhancement-mode Gallium nitride (GaN) high electron mobility transistors (HEMTs) under various test conditions.
Journal ArticleDOI
A Family of Quasi-Switched-Capacitor Circuit-Based Dual-Input DC/DC Converters for Photovoltaic Systems Integrated With Battery Energy Storage
TL;DR: In this article, a family of bidirectional dual-input dc/dc converters is proposed to combine a photovoltaic system and battery energy storage system, which utilizes a full-bridge, or half-bridge current-source circuit, as the primary side, and a quasi-switched-capacitor circuit as the secondary side.
