| Abstract |
This paper focuses on the Modular Multilevel Converter (MMC) with integrated magnetics foran Inductive Power Transfer (IPT) system applied to a 1 MW high-speed train. The MMC achieves zero-voltage switching (ZVS) through duty cycle pattern modulation, and an improved capacitor voltage balancing algorithm to enhance reliability against inter-leg imbalances is presented.A comparison between the MMC and Cascaded Hbridge (CHB) with integrated transformers was studied. While the CHB converter excels in efficiency and performance, the MMC is particularly suited for handling higher currents. The study presents an IPT system with five H-bridged modules for the CHB with integrated transformers and five sub-modules per arm for the MMC. Maximum efficiency exceeds 94\% at 1 MW, highlighting the strengths of both topologies in high-power applications. |
