A High-Efficiency Flyback Micro-inverter With a New Adaptive Snubber for Photovoltaic Applications
TL;DR: Based on the hybrid operation of interleaved flyback micro-inverter in discontinuous and boundary conduction modes (DCM and BCM), a novel adaptive snubber is proposed in this paper, which limits the drain-to-source voltage overshoot of the flyback's main switch during the turnoff process.
Proceedings ArticleDOI
AC circulating currents suppression in modular multilevel converter
TL;DR: In this paper, a proportional-resonant type minor loop is incorporated to regulate the most AC components of the circulating current to zero in addition to the DC regulation loop, which can also be applied to single phase MMC, which is not available in previous methods.
Journal ArticleDOI
7.2-kV Single-Stage Solid-State Transformer Based on the Current-Fed Series Resonant Converter and 15-kV SiC mosfet s
TL;DR: In this paper, a two-level single-stage direct ac-ac converter for realizing a 7.2kV medium-voltage (MV) solid-state transformer (SST) based on 15kV SiC mosfet s is proposed.
Proceedings ArticleDOI
Short-circuit capability of 1200V SiC MOSFET and JFET for fault protection
TL;DR: In this article, the short-circuit capability of power switches is studied and analyzed at 400V DC bus voltage, and the SiC MOSFET and SiC JFET showed different types of temperature coefficient.
Journal ArticleDOI
A Medium-Voltage Hybrid DC Circuit Breaker, Part I: Solid-State Main Breaker Based on 15 kV SiC Emitter Turn-OFF Thyristor
TL;DR: In this paper, a hybrid dc circuit breaker employing a Thompson coil based ultrafast mechanical switch (MS) with the assistance of two additional solid-state power devices was proposed for the protection of the dc power systems in electric ships.
