Abstract:

A zero voltage transition (ZVT) circuit is proposed for DC-DC boost converter circuit which is used for power factor correction. The main application of this is for on-Board Battery charger application in an Electric Vehicle as well as battery storage applications for home appliances. Zero voltage transition (ZVT) circuit consists of a high frequency MOSFET, an inductor, and diode. An inductor (resonant inductor) resonates with capacitances of the main MOSFET switch and main diode of boost converter during turn-on transition with this, auxiliary MOSFET of ZVT circuit itself turns-off with zero current switching in consequent to reduction in power loss across the main MOSFET. The time of conduction of ZVT circuit is very small compared with the main boost converter. So auxiliary ZVT circuit consumes a small amount of output power which can be neglected. The combination of a capacitor and low-frequency diode which can call it as a discharge mechanism which helps to transfer the energy from the auxiliary ZVT circuit to the output. The operating principles, waveforms, results, comparison and the design of auxiliary ZVT circuit are discussed. The MATLAB simulation of the proposed topology also presented in detail.
