Abstract :

A low loss auxiliary zero voltage transition (ZVT) circuit is proposed for boost based power factor correction circuit for on-Board Battery charger application in an Electric Vehicle and battery storage applications for home appliances. The ZVT circuit consists of an auxiliary MOSFET, a resonant inductor, and a diode. A resonant inductor resonates with capacitances of the main MOSFET and main diode during turn-on transition along with this, auxiliary MOSFET itself turns-off with zero current switching, and as a result of this power loss across the main MOSFET get reduces. The conduction time of the ZVT circuit is very small as compared with the main boost converter, due to this, the auxiliary circuit consumes a small amount of output power which is negligible. A discharge mechanism consists of a capacitor and low-frequency diode which helps to transfer the energy from the auxiliary ZVT circuit to the output. The operating principles, waveforms, and the design of auxiliary ZVT circuit are discussed. The MATLAB simulation of the proposed topology also presented in detail.
