Abstract

The paper proposes and analyzes an impulse commutation based zero current switching (ZCS) current-fed three-phase push-pull dc/dc converter. The classic problem of turn-off spike in current-fed converters has been addressed via impulse commutation. A small high frequency capacitor is used to solve the problem. The resonance between the leakage inductances and the parallel capacitors facilitates zero current operation of the devices via impulse commutation and confines the maximum switch voltage to Vo/n naturally. Variable frequency modulation aids in regulating the output voltage. Impulse commutation offers reduction in the component count (snubber or active-clamp) and superior performance with low circulating currents. Simulation results using PSIM 9.3 and experimental results on 1kW laboratory prototype have been demonstrated to corroborate the aforementioned claims.
