摘要

鉴于传统Boost变换器结构电压抬升能力不足

提出一种基于耦合电感和倍压单元的二次型DC-DC变换器。该变换器将耦合电感与电压倍增单元组合

在中低占空比下具有较高的电压抬升能力。利用无源钳位电路吸收漏感产生的电压尖峰

减少能量损耗。双开关同步运行

控制简单

且共同承受电压应力

使得每个开关管电压应力较低。介绍该变换器的拓扑结构、工作原理、稳态分析。最后搭建一台200 W的实验样机

在0.4占空比下实现20倍电压增益

最高效率可达98.41%

证明变换器的可行性。

Abstract

Due to the insufficient voltage boosting capability of the basic Boost converter

a quadratic DC-DC converter based on coupled inductor and multiplier cell is proposed. The converter combines the coupled inductor with the voltage multiplier cell to achieve high voltage gain at low and medium duty cycles. The passive clamp circuit is used to absorb the voltage spike generated by the leakage inductance and reduce the energy loss. The two switches operate synchronously

the control is simple

and they share the voltage stress

so that the voltage stress on each switch is low. The topology

working principle and steady-state analysis of the converter are introduced. Finally

a 200 W experimental prototype is built

which achieves a voltage gain of 20 at 0.4 duty cycle and a maximum efficiency of 98.41%

proving the feasibility of the converter.
