I have a boost converter followed by an inverter to supply a load. The output frequency of the inverter is variable but relatively low (~50 Hz). The issue I'm facing is the second harmonic current (at twice the output frequency) which is far from negligible. The evident solution would be to have high enough bulk capacitance, but due to size constraints I can't. Do you know of any other solution? Like a non-standard compensation on the boost side?
Thanks in advance
