Quasi square wave inverter
WebTable 8.3 and 8.5 can be used to predict the THD for the ouput current of the inverter connected to RL load. Higher order harmonics are assumed to contribute little power and effect, so they can be neglected. To evaluate the THD for the output voltage of the inverter, higher order harmonics should be taken into account. -tammat- WebApr 22, 2009 · Modified square wave is the actual wave form.
