A new inverter using two thyristors in place of two freewheeling diodes is presented. This inverter allows a reversible DC/AC converter to be implemented. This converter can control the inrush-current and allow bridge full-disconnection at stand-by to suppress undesired losses. This is achieved by a full-silicon solution without the need of any inrush-current limiting resistor and or mechanical relays. In this paper, PSPICE simulation results are presented to validate the converter operation. Experimental results are given to discuss the on-state threshold voltage difference between a slow diode, using in a classic inverter, and a thyristor used in this new topology.
