To overcome voltage stress existed in the inverter with high frequency AC pulse link, singlepolarity and double polarities phase shifting control strategies were proposed and studied in this paper.
为克服高频脉冲交流环节逆变器存在的电压过冲现象，本文提出和研究了单极性、双极性移相控制策略。

Polarity: a single halo extending further in a certain direction.
极性：单独的光圈会向某一个特定方向扩展。
