Dear All,

In my Three Phase Inverter application, for closed loop control (Voltage and Current control) i need to take feedback of Voltages and Currents . My doubt is whether i need to have output LC filter and obtain sinusoidal waveforms for taking feedback OR whether the stepped waveform is sufficient.

If i use stepped waveform ie without using LC filter, and give it to ADC of microcontroller, does it affect the accuracy in calculations and control?
