The paper presents the design and analysis of an un‐regulated isolated DC–DC converter using wide band gap (WBG) devices for low‐voltage, high current applications. Un‐regulated isolated DC–DC converter uses a passive rectifier stage at the front end to connect to the utility grid. This will have a voltage stress of 480–780 V DC at the input of the isolated DC–DC converter. For the evaluation, SiC devices are used at the primary side and GaN devices at the secondary side of the converter. Later on the conclusion, a regulated isolated DC–DC converter, which uses an active PFC at the front‐end, will be recommended for having less chip area utilisation, less components and efficient magnetics as far as DC–DC converter is concerned.
