To provide a thyristor rectifier with pulsewidth modulated operations and zero-voltage and/or zero-current switchings, two resonant switches, which consist of LC resonant circuit plus other switching devices and diodes, are connected with a thyristor bridge in series and in parallel. The arrangement tested, using four insulated-gate bipolar transistors, is implemented to investigate the operations under the sinusoidal pulsewidth modulation. The experimental results confirm that AC current can be sinusoidally waveshaped with reduced harmonic distortion.
