Abstract

The dual-PWM frequency control system needs to set a filter on the grid side to suppress harmonic current. By analyzing the difference of operation characteristics between LCL filter and L filter, the parameters of L filter are optimized in order to reduce the volume of rectifier, taking into account the filtering effect, current fast tracking ability and system fast response ability; A PWM rectifier control algorithm based on L-filter is proposed, and the parameters of voltage and current loop controller are adjusted to realize the control of fast current tracking, stable voltage output and power factor of 1 on the grid side. The simulation and experimental results verify the correctness of L-filter design and the effectiveness of PWM rectifier control algorithm
