Design &Implementation of Single Switch DC-DC Resonant Converter for Hybrid Vehicle

Abstract

In this paper, a innovate single-switch resonant DC-DC power converter for a hybrid vehicle with renewable energy generation operations for the hybrid vehicle are developed. This circuit Scheme combines a innovate resonant DC-DC converter with energy-blocking diode with zero-current switching (ZCS) and zero-voltage switching (ZVS). The output level of the innovate single-switch DC-DC resonant converter was filtered by using direct-current(DC) output blocking diode. To decrease the price of the control circuits. For power energy conversion only one active power switch was provided. The PWM at a constant duty cycle, the fixed switching frequency is used to control the active power switch. When the DC-DC resonant converter works at irregular conduction mode. At that time inductor current which travels through the resonant tank might reach the (ZCS) Zero Current Switching of the energy-blocking diode. The resonant tank consequently, a high energy modification efficiency is confirmed. Working propositions are analyses and derived are achieve for proposed resonant DC-DC converter under different working modes based on the equivalent circuit. The working principles of the resonant DC-DC converter were authenticated powered load system by employing a Photovoltaic (PV). Given properly selected circuit parameters, The ZVS can work with active power switch the planned topology of 97.3% can be obtained with measured energy conversion efficiency.
