voltage commutation

In this paper, some problems about IGBT's operation characteristics are discussed. A driving mode called zero voltage commutation and zero current commutation ( ZVC/ ZCC) technique with high efficiency and safety is introduced.

对IGBT的工作特性及存在的问题进行了深入探讨，详细介绍了用于提高大功率IGBT电桥的开关效率和安全性的ZVC／ZCC驱动模式。

The proposed auxiliary commutation circuit consists of one resonant inductor and two bidirectional switch, which provides the ZVS condition to the main switch without increasing voltage or current stresses.

提出的辅助变换电路由一个谐振电感和两个双向开关组成，此电路没有增加主开关的电压和电流应力，却给主开关提供了ZVS的条件。

This commutation method does not require any current or voltage sensors and it only depends on the RB-IGBT collector-emitter voltage sensing unit on the drive board to acquire the necessary information.

该换流策略不需要任何电流电压传感器，仅依靠本文为RB-IGBT设计的驱动保护电路中的集-射电压检测单元即可获取换流所需信息。
