LC Filter for Three phase inverter

Submitted by dbz_10 on Sun, 05/24/2020 - 11:58


I am designing a DC Link Converter with an output power of 60kVA with a phase voltage of 115V RMS. I am using Sine PWM inverter with 10kHz as switching frequency. When I connect the rectifier's output as input to the inverter the output current waveform gets distorted but the voltage waveform looks neat. When I use a DC source as input to the inverter both the waveforms are neat. I have a doubt where the problem lies, is it the filter on the output side or the rectifier's output.

Kindly help me 

Thank you
