A high-pulse constant frequency inverter for DC and variable frequency generation sources

Abstract

There are many possible sources of DC and variable frequency AC power, yet standard commercial appliances require constant frequency AC power. This paper present an alternative inverter principle, which simplifies control hardware and reduces switching losses compared to PWM techniques, yet provides acceptable voltage and current waveforms. This is achieved by the use of reinjection techniques, which are applied to a forced commutated inverter.<>
