众所周知，单相PWM整流器直流母线上存在二阶谐波电流和相应的涟漪电压。通常使用总线中的大容量电容器来过滤低频谐波电流，这导致低功率密度。提出了一种有效减小储能电容的有源涟漪储能方法。给出了前馈控制方法和设计考虑。仿真和15kW的实验结果提供验证的目的。
It is well known that there exist second-order harmonic current and corresponding ripple voltage on dc bus for single phase PWM rectifiers. The low frequency harmonic current is normally filtered using a bulk capacitor in the bus which results in low power density. This paper proposed an active ripple energy storage method that can effectively reduce the energy storage capacitance. The feed-forward control method and design considerations are provided. Simulation and 15kW experimental results are provided for verification purposes.
