Abstract

The characteristics and the superiority of the efficient snubber network for Class-D series resonant inverters are addressed in detail by comparison with conventional snubbers, i.e., the lossless capacitive snubber and the RC snubber, with respect to switching losses, overvoltage stresses, high-frequency resonant current stresses, and overall efficiency. Also, the optimal design scheme for it is considered and the analytical equations are derived in order to provide a straightforward and easy-todesign tool. The validity of the theoretical description is verified by testing on a 29-kHz MOSFET Class-D series resonant inverter rated at 1.2 kW.
