摘要

本文讨论了高频环节逆变器中交流-交流循环变换器级的各种抑制振荡的方法。由于转换电路的寄生参数，这种振荡发生在开关的自然换相之后。本文对循环变换器级的谐振过程进行了数学分析，然后对不同的缓冲电路进行了比较分析，使振荡的影响最小化。通过软件模型和1kw直流-交流变换器的实验样机验证了理论分析的正确性。

Analysis of Oscillation Suppression Methods in the AC-AC Stage of High Frequency Link Converters

This paper addresses various oscillation suppression methods in the AC-AC cycloconverter stage of a high frequency link inverter. Such oscillations occur after the natural commutation of the switches due to parasitic parameters of the converter circuit. A mathematic analysis of the resonance process in the cycloconverter stage is presented, followed by a comparative analysis of different snubber circuits that allow to minimize the effect of oscillations. The theoretical analysis is verified with software models and experimental prototype of 1 kW DC-AC converter.
