一种具有非线性变换比的双变压器有源钳位正激变换器

This paper proposes a dual-transformer active-clamp forward converter (DT-ACFC) with nonlinear conversion ratio (NCR), which combines two forward converter units. Since only two active switches are needed, the cost and the circuit complexity can be lowered. To reduce switching loss, the proposed converter fulfills zero-voltage switching by employing the leakage inductance of the transformer and ad...
