Abstract

Novel double- and triple-rectifier systems coupled with a harmonic draining transformer and a harmonic blocking transformer are proposed. Both the systems can produce sinusoidal line currents when the dc output currents of the diode bridges are controlled in a quasi-triangular- or quasi-trapezoidal-shape, respectively. In comparison with a conventional PWM converter, the proposed systems have the advantages of lower switching-frequencies and smaller switching-currents.
