Abstract
Fairly sophisticated controls are needed to achieve concurrent multiple objectives of pulse-width-modulation (PWM) converters. The objectives may include near-sinusoidal current waveforms, fine DC voltage or current regulation, and specified power factor. The use of a system of three high-speed digital signal processors to implement these controls in real time is described. The voltage angle lock loop control of a voltage source (boost-type) converter for a high-voltage direct-current system is presented. Experimental results confirm that the digitally controlled system can realize the full potential of the PWM converter.<>
