Abstract
Due to large application of induction motors in industries, it has become prudent to work on its speed control. As the inverter provides better sinusoidal voltage or current, speed control of machines becomes more fine. It is possible only if inverter gets better gate pulses. Hence for testing of quality of inverter output voltage or current, %THD and switching frequency are two important parameter. It also contain the output voltage or current at 3k Hz switching frequency.
