Abstract :

Conventional chargers utilize low frequency (50Hz) transformers which are bulky, less efficient and thus costly. As a solution to this, utilization of controllable high frequency power supply with high dynamic and steady state current regulation, performance can be improved. In the design robustness, small size and low weight, low complexityand high efficiency are the defining criteria. The most suitable approach for a 1.1 kW battery charger module for power supply application is the high frequency Full–Bridge Zero Voltage Switching (FB–ZVS) charger with an isolation transformer.This module not only gives the advantage of zero voltage switching for a wide load current range, it also provides reduced Electromagnetic Interference (EMI) and reduced component stress compared to standard PWM based modules. In this paper a FB–ZVS based charger with 1.1kW power rating is designed for modern battery charging applications. IGBTs are utilized at 25 kHz switching frequency for high efficiency and control bandwidth. The output current of the module is controlled via an ATmega128 microcontroller. The performance of the designed charger is evaluated via the computer simulations and the experimental study of the constructed prototype. The main aim of representing this paper is to deploy this project on commercial basis in market.
