摘要 该文围绕交错Boost变换器稳态和动态性能综合优化这一问题展开研究。通过采用反向耦合电感代替传统分立电感,利用其在一个开关周期的不同时间段内具有不同的等效电感这一优势,可以同时实现对变换器稳态和动态性能的优化。在高频工作条件下,采用反向耦合电感可以进一步减小功率电感损耗,提升变换器效率。该文以两路交错Boost变换器为例,首先对耦合电感的等效电感进行理论推导;然后对变换器的稳态和动态性能进行理论分析,指出反向耦合电感在改善变换器稳态和动态性能方面的优势;最后结合GaN功率开关器件,搭建一台开关频率为500kHz,额定功率为500W的实验样机,并与采用分立电感的交错Boost变换器进行实验对比。结果证明,采用耦合电感可以提升变换器稳态和动态性能,验证了该文理论分析的正确性。

Abstract:This paper focuses on the comprehensive optimization of the steady-state and dynamic performance of the interleaved Boost converter. By using reverse-coupled inductors instead of traditional discrete inductors and taking advantage of their different equivalent inductances in different time intervals of a switching cycle, the steady-state and dynamic performance of the converter can be improved at the same time. Under high- frequency operating conditions, the use of reverse-coupled inductors can further reduce inductor losses and improve converter efficiency. This paper takes two-channel interleaved Boost converter as an example. First, the equivalent inductance of the coupled inductor is theoretically derived, and then the steady-state and dynamic performance of the converter is theoretically analyzed. The advantage of reverse-coupled inductors in improving the steady-state and dynamic performance of the converter is pointed out. Finally, combined with GaN FETs, an experimental prototype with a switching frequency of 500kHz and a rated power of 500W was built, and compared with the interleaved Boost converter using discrete inductors. The experimental results prove that the use of coupled inductors can improve the steady-state and dynamic performance of the converter, which verifies the correctness of the theoretical analysis in this paper.
