浅谈几种谐振变换器的控制方法

Several Control Strategies of Resonant Converter

阐述了谐振变换器的变频、移相、自持振荡、自持振荡移相、最优轨迹等五种控制方法的实现原理,从其暂态响应、频率控制范围、软开关性能三个主要方面进行了对比研究,并做了仿真验证。

This paper introduces five control strategies of resonant converter： variable frequency control, phase shift control, self-sustained oscillation control, self-sustained phase shift control and optimal trajectory control. The paper expatiate the principle of them, and makes comparison of the transient response, switching frequency range, soft switch capabil ity of the five control strategies, finally validates the analysis with simulation.
