ABSTRACT:
The RMS voltage of the output sine wave of a power inverter is regulated by pulse width modulation (PWM) of the rectangular waveform fundamental signal of the inverter bridge with a single sliding notch in each half cycle of the rectangular wave, each notch having a pulse width and position in the wave which is dependent on the required attenuation of the RMS value, and which may be varied, in a continuous manner, between a variable pulse width edge notch, a fixed pulse width notch which slides from an edge notch to a center notch position, and a variable pulse width center notch.
