This paper proposes a new improved zero-voltage switching isolated boost converter with coupling inductors. With the traditional advantages of smaller input current ripple, low diode voltage rating, and low transformer turns ratio of boost half bridge topology [ being retained, the proposed converter makes it much easier to realize zero voltage switching of primary switches compared with conventional converters.

An isolated high step-up DC-DC converter with a continuous input current is proposed. The proposed converter consists of two converter cells — a boost converter cell at the input stage for a low input current ripple and a DC-DC converter cell for high voltage gain. Zero-voltage-switching of power switches are achieved and the leakage inductance of the transformer alleviates the reverse-recovery problems of the output diodes. Therefore, the proposed converter achieves high efficiency. Detailed analysis and design of the proposed converter are carried out. A prototype of the proposed converter is developed, and its experimental results are presented for validation.
