Sinusoidal PWM 3-Phase Inverter

Dc-to-ac converters are known as inverters. The function of an inverter is to change the dc input voltage to an ac output voltage of desired magnitude and frequency. The output voltage waveforms of ideal inverters should be sinusoidal. However, the output of practical inverters contains harmonics. For high power applications, low distorted sinusoidal waveforms are required. Harmonic contents could be minimized by the use of high-speed. semiconductor switching techniques
Inverters are widely used in industrial applications-
motor drives, UPS, induction heating, standby power supplies, etc.
input may be a battery, fuel cell, solar cell, or there dc source
Dc-to-ac inverters can make smooth transition into the rectification mode, where the flow of power reverses from the ac side to the dc side. Two types of inverters: single-phase inverters and three-phase inverters.
