PWM Techniques: A Pure Sine Wave Inverter

output type: square wave, modified-sine wave and pure sine wave. Off-the-shelf inverters are generally either square wave or modified-sine wave. These types of inverters are less expensive to make and the output, though delivering the same average voltage to a load, is not appropriate to delicate electronic devices which rely on precise timing.
