Abstract
A study on the use of gate turn-off (GTO) thyristors as zero-turn-off-time thyristors in series-resonant inverters is presented. A comparative study on the power switches and their commutation mechanisms in series resonant inverters has been made to demonstrate the advantages of this operation mode of GTO below the resonance frequency Zero-turn-off-time operation of GTO thyristors is detailed, and the design of a highly reliable triggering circuit for a self-protected GTO inverter leg is presented. The performances of two series-resonant, inverters using, respectively, asymmetric thyristors and zero-turn-off-time GTOs are studied and compared.<>
