Circulating Current Analysis of Cascaded H-Bridge Matrix Converter for High Voltage Low-Frequency AC Transmission
摘要
Abstract
The high voltage low-frequency AC transmission has many advantages in off-shore wind power, metropolis power supply, AC cable reconstruction for enlarging capacity. Herein, high voltage AC-AC converter is one of the significant technologies. As the direct AC-AC converter, the cascaded H-bridge matrix converter (CHB-MC) is an appropriate converter owing to its high performance in low frequency conditions. In this paper, DC voltage fluctuation and circulating current (CC) of CHB-MC were analyzed with common term formula based on the CC equivalent circuit. The frequency and magnitude of characterized frequency of CC were derived, and the relevant parameters of CHB-MC were also analyzed in detail. The simulation on PLECS platform verified the analyses above.关键词
