基于电压定向状态平面反馈控制的单相双级整流器LLC变换器二次谐波电压抑制

Second harmonic output voltage ripple in a single-phase grid-connected rectifier can degrade the system's performance. In this letter, a voltage-oriented state plane feedforward control is proposed to suppress the second harmonic output voltage ripple for the LLC converter, which serves as the backstage of the dual-stage single-phase rectifier. Herein, the desired switching frequency of the LLC co...
