Modified Sine-Wave Inverter Enhanced

Abstract

Sine-wave inverters, which are used for clean, near sine-wave outputs for medical, instrument and other critical applications are discussed. These inverters produce sine waves with total harmonic distortion (THD) in the range of 3%. the design for these inverters use pulse-width modulation (PWM) to produce a pulsed waveform that can be filtered relatively easily to achieve a good approximations to a sine wave. a category of sine wave inverter is called modified square waves, which are basically square waves with some dead spots between positive and negative half-cycles. Altering the waveform produced by a modified sine-wave inverter reduces distortion products, while permitting use of efficient switching techniques. the modified inverter design will reduce switching losses and will save power regardless of the output power level design.
