topology has some significant advantages over the other topologies, such as lower conduction losses of the switches, lower input
current ripple, and the best utilization of the transformer [33].
Therefore, the current-fed half-bridge topology can be superior
to other topologies for the module-integrated dc–dc converter.
However, it has some disadvantages, such as starting problem,
full-load range problem, and high-voltage surges across the turnOFF switch caused by the leakage inductor of the transformer.
Some improved topologies have been presented to solve these
problems [33]–[36], illustrated in Fig. 4
