PWM Techniques: A Pure Sine Wave Inverter

Apr 27, 2011 · transformer. The inverted signal itself is composed of a pulse-width-modulated (PWM) signal which encodes a sine wave. The duty cycle of the output is changed such that the power transmitted is exactly that of a sine-wave. This output can be used as-is or, alternatively, can be filtered easily into a pure sine wave.
