摘要

本文给出了三相主动箝位谐振直流链路逆变器的扩展数学模型。详细介绍了利用模拟σ - δ调制器预测谐振直流链路电流的控制方法。通过仿真研究了逆变器在电阻性、感性和容性负载下的运行情况。结果表明，即使在谐振电流反转和低调制指数的情况下，逆变器也可以在零电压开关情况下工作于所有类型的负载。

A Short Overview of Active-Clamped Resonant DC Link Inverter

In this manuscript an extended mathematical model of a three-phase actively-clamped resonant dc link inverter is shown. The control approach based on usage of the analog sigma-delta modulator with prediction of resonant dc link current is explained in detail. The inverter operation under resistive, inductive and capacitive load is examined by simulations. It is shown that inverter can work with all types of loads under zero-voltage switching circumstances even when having resonant-current reversals and with low modulation index.
