In order to get a better power quality environment, a comparison has been made between the performance of LLCL filters, LCCL filters, and hybrid filters in an analog brake regenerative power feed system. Based on the analysis of three-phase voltage, current before and after filtering and harmonic (FFT) among the observed parameters, the optimal combination filter (LCL filter + LLCL filter) can achieve a good harmonic suppression effect of the brake regenerative feeding system with a lower THD value.
