This paper illustrates the study of three isolated zero<br>
voltage switched (ZVS) PWM full bridge (FB) converters to charge<br>
the high voltage battery in the charger of electric vehicle (EV).<br>
EV battery chargers have several challenges such as high efficiency,<br>
high reliability, low cost, isolation, and high power density. The<br>
cost of magnetic and filter components in the battery charger is<br>
reduced when switching frequency is increased. The increase in the<br>
switching frequency increases switching losses. ZVS is used to reduce<br>
switching losses and to operate the converter in the battery charger<br>
at high frequency. The performance of each of the three converters<br>
is evaluated on the basis of ZVS range, dead times of the switches,<br>
conduction losses of switches, circulating current stress, circulating<br>
energy, duty cycle loss, and efficiency. The limitations and merits of<br>
each PWM FB converter are reviewed. The converter with broader<br>
ZVS range, high efficiency and low switch stresses is selected for<br>
battery charger applications in EV.
