DC-AC power converters (inverters) are widely used today mainly in uninterruptible power supply systems, AC motor drives, induction heating and renewable energy source systems etc., High-Frequency Inverters (HFI) have been applied in DC-AC power conversion in which size and weight are of important considerations. The basic such model uses an RCD snubber to dampen the voltage spike which occurs due to transformer leakage inductance. But this causes a snubber power loss which reduces the system efficiency. Whereas the implementation of the regenerative snubber reduces the voltage spike and at the same time snubber stored energy is fed back to the input/output side to improve the system efficiency. This paper presents the HFI with active regenerative snubber to recover the snubber energy into the output side. MATLAB/SIMULINK simulation results and experimental results are presented.Keywords
