摘要

收起

传统交错并联型Boost变换器在升压电源系统中应用广泛，虽然理论上可以通过增大占空比来获得更高的电压增益，但受限于功率二极管反向恢复时间以及各寄生参数等非理想因素的影响，通常电压增益不超过4倍，且随着输出电压与功率的增加，增益极限值将进一步降低。为解决上述问题，提出了高升压比Boost变换器，在同等输入电压等级的前提下可拓宽输出电压范围，并将变换器内的输入、输出滤波电感集成于一副磁心中，在提高功率密度的同时消除传统Boost变换器内固有的右半平面零点，从而大幅提高输出动态响应速度。另外，分析了变换器的工作原理，总结其特性，讨论了耦合电感的磁心选择方法，最后通过仿真与实验验证了方案的有效性。

Abstract

收起

The conventional interleaved parallel Boost converter is widely applied in step-up power supply systems. Although it is theoretically possible to obtain a higher voltage gain by increasing the duty cycle, the voltage gain usually does not exceed 4 times due to the influence of non-ideal factors such as the reverse recovery time of diodes and parasitic parameters. In addition, the gain limit will further decrease with increases in output voltage and power. To solve these problems, a Boost converter with a high voltage gain is proposed to expand the output voltage range at the same input voltage level. Meanwhile, the input and output filter inductors in the converter are integrated into one pair of magnetic cores, so as to eliminate the inherent right half plane zero in conventional Boost converters while improving the power density. Therefore, the output dynamic response speed is significantly improved. The working principle for the converter is analyzed, its characteristics are summarized, and the magnetic core selection method for the coupled inductor is discussed. Finally, the effectiveness of the proposed scheme was verified through simulations and experimental results.
