Proceedings ArticleDOI
A high power density single phase PWM rectifier with active ripple energy storage
TL;DR: In this paper, the authors proposed an active ripple energy storage method that can effectively reduce the energy storage capacitance, and the feed-forward control method and design considerations are provided.
Journal ArticleDOI
Impact of Interleaving on AC Passive Components of Paralleled Three-Phase Voltage-Source Converters
TL;DR: In this article, the impact of interleaving on harmonic currents and voltages on the ac side of paralleled three-phase voltage-source converters was analyzed, considering the effects of modulation index, pulsewidth-modulation (PWM) schemes, and interleave angle.
Journal ArticleDOI
Active Gate Driver for Crosstalk Suppression of SiC Devices in a Phase-Leg Configuration
TL;DR: In this paper, the authors proposed two active gate assist circuits to suppress crosstalk on the basis of the intrinsic properties of SiC power devices, and the experimental results show that both active gate drivers are effective to suppress CRSST, enabling turn-on switching losses reduction by up to 17% and negative spurious gate voltage minimization without the penalty of decreasing the switching speed.
Journal ArticleDOI
Temperature-Dependent Short-Circuit Capability of Silicon Carbide Power MOSFETs
Zhiqiang Wang,Xiaojie Shi,Leon M. Tolbert,Fred Wang,Zhenxian Liang,Daniel Costinett,Benjamin J. Blalock +6 more
TL;DR: In this paper, the authors present a comprehensive short-circuit ruggedness evaluation and numerical investigation of up-to-date commercial silicon carbide (SiC) MOSFETs.
Proceedings ArticleDOI
A D-Q Frame Controller for a Full-Bridge Single Phase Inverter Used in Small Distributed Power Generation Systems
TL;DR: In this paper, a Direct-Quadrature (DQ) rotating frame control method for single phase full-bridge inverters used in small hybrid power systems is presented, where a secondary orthogonal imaginary circuit is created to provide the second phase required for the transformation.
