Hi,
I try to design LC filter in H-bridge, where load is Peltier module. I wanted to create heat/cool options.
For values shown below, cutoff Frequency is 13kHz. I don't want to overdo. Is triangle wave sufficient or should I change freq. to get sine wave? When suppression is high, there are some issues - lower currents and voltage.
One branch of H-bridge.
I decided use 7.8kHz, then
