A Lightweight Design on Mobile Power Supply with Fuel Cell Energy
In this paper, a MMC based fuel cell (FC) system (MMC-FCs) is proposed for mobile power supply. The synchronous switch modulation based on high-frequency link (HFL) can realize the voltage control of DC bus of interconnected full-bridge. It also helps to suppress the fundamental and 2<sup>nd</sup>order-frequency ripple current of the sub-module (SM), thus greatly
