Hello, 

Shouldn't the load voltage waveform be sinusoidal in case of a sinusoidal PWM inverter.

I can see a sine wave to generate switching but the load voltage isn't sinusoidal.

thanks,
Ram

  • Hi Ram,

    The load signal mentioned in the results tab displays only positive half of the output. You may try using differential probe across the RL load. I have attached a snapshot of output across RL load. And obviously you can see spikes as a result of switching of IGBT.

     Thanks,
