Research of SPWM Algorithm Based on Equivalent Area Compensation

Abstract:

This paper presents a SPWM algorithm based on equivalent area compensation. The algorithm could make the output fundamental wave keeps linear with the modulation wave while the modulation M is more than 1 to extend the linear range and improve the accuracy of the output waveform by pre-shaping modulation function. Experiments show that this algorithm has such advantages as high voltage utilization , small harmonic loss，simple calculation and strong real-time.
