Investigation of a hybrid converter with 16:1 wide voltage operation

Abstract This study investigates a hybrid zero‐voltage switching converter for dc–dc converters on railway vehicle applications or solar PV power conversion applications. The dc–dc converters used in railway applications demand to have at least 30% to 40% input voltage variation in order to meet the...
