#SPWM (#sinusoidal_pulse_width_modulation) microcontrollers are used in #pure_sine_wave_inverters to generate more accurate AC sine wave.
This #microcontroller can store the required commands, to generate the necessary waveform for the #inverter, through proper design of switching pulses.
The basis is to use an #H_bridge with #IGBT_switches, to reverse the load current, by inverting the DC voltage across the load terminals, alternately.
All these things are explained well in this video, with fine animation work.

Thank you.
