摘要

提出了一种三电平电容箝位逆变器的零电压开关方案。所提出的小额定辅助电路既保证了主开关的零电压开关和辅助开关的零电流开关，又稳定了逆变器的箝位电压。该方案防止任何电压或电流尖峰发生在主或辅助开关上，并且不需要调制约束。详细介绍了该方案的运行、分析、设计和测试。

Soft-switched three level capacitor clamping inverter with clamping voltage stabilization

This paper proposes a zero voltage switching scheme for a three-level capacitor clamping inverter. The small rating auxiliary circuit proposed ensures not only zero voltage switching of the main switches and zero current switching of the auxiliary switches, the clamping voltage of the inverter is also stabilized. The scheme prevents any voltage or current spikes from occurring over the main or auxiliary switches and no modulation constraints are necessary. Operation, analysis, design and testing of the scheme are detailed.
