Popis:	This article presents a novel isolated dc–dc converter circuit topology, which is able to offer high performance for a wide range of operating conditions. The prominent features of the proposed circuit topology include its direct power transfer (DPT) capability, quasi-rectangular waveform for the input current, and soft-switching performance for a wide range of operating conditions. The amount of power processed by the power switches and transformer is reduced through DPT. In addition, the quasi-rectangular waveform of the input current decreases its peak and root-mean-square values, leading to reduced conduction losses associated with the magnetics and power semiconductors. In the proposed structure, the power switches benefit from zero-voltage-switching characteristics, while the output diodes operate under zero-current-switching conditions. Thus, the proposed topology minimizes both the conduction and switching losses, thereby improving the overall efficiency. Extensive simulation and experimental results are provided to verify the feasibility of the proposed circuitry and demonstrate its superior performance.
