Ultrasonic carrier PWM converter employing IGBT in the near future
The authors describe an ultrasonic PWM (pulse-width modulated) carrier-frequency current sourced power converter employing IGBTs (insulated-gate bipolar transistors) with a self-aligned DMOS structure. The sinusoidal waveform (rather than the ultrasonic corrected triangular waveform) method is employed for the PWM pulse pattern to operate the converter. Because of the ultrasonic PWM carrier frequency, the converter changes the AC line current waveform to a sinusoidal waveform; thus, the convertor's filter can be small, and its displacement factor is improved.<>
