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.
