摘要

AC/DC power electronic transformer is the core of the energy conversion device as a micro grid having a multi-port, high-capacity, high efficiency functions. Bipolar failure is one of the typical failures, causing the system does not work. This article aims to analyze the post bipolar DC microgrid faults in the AC/DC power electronic transformer is proposed to suppress over-voltage topology, analy...
