Comparative study of electronic transformers using resonant and nonresonant switching converters
Five different topologies for AC choppers are studied. Among them are the soft switching power converters ZCS (zero current switching) QSRC with three switches, half-bridge ZCS QSRC, ZVS (zero voltage switching) step down converter with two switches, and ZVS step-down converter with small current ripple. They are applicable to AC choppers requiring four-quadrant operation. The two-step driving-down converter has the lowest current ripple and acceptable switching loss and is the most suitable for implementing a small, lighter, and more economical high-power system (>1 kVA).<>
