<p>A boost rectifier is provided with an ultra high speed diode (D) in its direct current rail to reduce diode reverse recovery loss with or without implementing a soft switching technique. Full zero-voltage-transition (ZVT) as well as zero-current transition (ZCT) may also be achieved by adding a simple auxiliary network (Lr, Daux, Saux) across the DC rail which operates only during the short turn-on transients of the bridge switches (Sap-Scn). Similarly, a simple, inexpensive auxiliary circuit can be added to the DC rail of a conventional voltage source inverter shown to implement both ZVT and ZCT.</p> |
