Abstract :
A control strategy for hard switching high power PWM rectifiers, based on carrierless volt-second (flux) control is presented. Insights from the fish method yield switching rules in the synchronous frame such that, even during major setpoint changes, none of the switches ever violates a pre-determined minimum pulse width. The control method realizes outstanding transient behaviour at low switching frequencies and allows a small DC-link capacitance, low inductance loads as well as nonequal dwell-times. Experimental data of a small DSP-controlled 1 kW IGBT PWM rectifier is presented
