Abstract In this paper, a novel boost DC/DC converter is proposed. The existence of the three-winding coupled inductor in the proposed topology causes an increase in voltage gain. Another advantage of suggested topology is that by reducing the turn’s ratio of the coupled inductor the voltage gain of converter is increased. In the proposed converter the stored energy in the leakage inductance is recovered by utilizing a passive clamp circuit. Moreover, in the proposed topology, voltage stress on the main switch is decreased. As a result, a power switch with lower resistance RDS (ON) and the lower number of windings turn are caused to reduction of power losses. Operation rules and steady-state analysis of the proposed converter are explained completely. In order to evaluate the effectiveness of the proposed converter, a 200 W laboratory prototype is implemented. Experimental results approve the theoretical analysis of the proposed high step-up converter.

基于三绕组耦合电感的新型高升压DC-DC变换器

摘要 本文提出了一种新型升压DC/DC转换器。所提出的拓扑中三绕组耦合电感的存在会导致电压增益的增加。建议拓扑的另一个优点是，通过降低耦合电感的匝数比，可以增加转换器的电压增益。在所提出的转换器中，泄漏电感中存储的能量通过使用无源钳位电路来恢复。此外，在所提出的拓扑结构中，主开关上的电压应力降低了。结果，导致具有较低电阻RDS(ON)和较低绕组匝数的功率开关以减少功率损耗。所提出的转换器的操作规则和稳态分析得到了完整的解释。为了评估所提出的转换器的有效性，实施了 200 W 实验室原型。实验结果证实了所提出的高升压转换器的理论分析。
