为了满足日益增长的电能需求，人们积极研究高压直流输电和柔性交流输电，以提高大容量电力传输效率。由于单个器件的电压和额定功率的限制，半导体器件的串联技术已应用于高压和大功率应用。本文提出了一种新的自换向开关串联连接方法。所提出的方法可以实现开关之间的自平衡，算法简单，并且减小了尺寸和额定值要求。实验验证了所提出方法的性能。
In order to meet the growing demand of electric energy, high-voltage dc transmission and flexible ac transmission has been actively investigated to improve the bulk power transmission efficiency. Due to the limitation of the voltage and power rating of a single device, series connection technology of semiconductor devices has been applied for high voltage and high power applications. In this paper, a new series connection method of self-commutating switches is proposed. The proposed method can realize self balancing among the switches with simple algorithm and reduced size and rating requirement. Experiments have verified the performance of the proposed method.
