A Dual Switch/Inductor Isolated High Voltage gain Based on Voltage Lift

In this paper, a novel dual switch/inductor isolated DC-DC converter configuration for high voltage gain applications is presented. The high voltage gain regulation of the proposed converters is achieved in a wide voltage range by employing an auxiliary transformer and voltage lift circuit. The auxiliary transformer couples the current paths of the two boost inductors, and the using voltage lift circuit led to the increased voltage gain. The presented converter is developed using the interleaving technique to achieve low-size filter components. The operation principle and steady-state analysis of continuous conduction mode (CCM) are used to determine voltage gain. Also, the simulation results are used to verify performance and validity.
