介绍了一种有源钳位软开关三相并网逆变器。通过增加一个简单的辅助支路，逆变器中的所有开关都可以实现零电压开关。不会造成额外的电压应力。提出了一种实现高效率功率变换的调制方案。特别是在网侧功率因数不统一的情况下，对调制方案进行了探讨。该调制方案在一台30kW的样机上得到了验证。
An active clamping soft-switching three-phase grid-connected inverter is introduced in this paper. With adding a simple auxiliary branch, all of the switches in the inverter can realize zero voltage switching (ZVS). No additional voltage stress will be caused. A modulation scheme to realize high efficiency power conversion is presented in this paper. Especially when the grid side power factor is not unity, modulation scheme is discussed. The proposed modulation scheme is verified in a 30kW prototype.
