A new Quantum Series Resonant Converter (QSRC) topology for pure sinewave 60 Hz ac chopper is proposed. It has three bidirectional switches and operates at high switching frequency with low switching loss. Bidirectional power flow is possible and the switches can operate at either zero current switching (ZCS) mode or zero voltage switching (ZVS) mode by slight modification. The QSRC is thought to be suitable for such a system with fixed voltage conversion ratio. The proposed converter is applied to an electronic 220/110 V transformer. The detailed analyses and the experimental results for 1 kVA are presented.
