Abstract :
PWM current-fed full-bridge dc-dc boost converters are typically in applications where the output voltage is considerably higher than the input voltage, such as fuel cell converters. The zero-voltage switching (ZVS) active-clamp converter is the most commonly used converter of this type. Zero-current switching (ZCS) techniques have also been used in current-fed full bridge converters, but not in fuel cell converters. In the paper, a comparison is made between the ZVS active-clamp full-bridge converter and a ZCS full-bridge converter. The operation of the two converters is discussed in detail and experimental results obtained from each converter are presented and compared.
