Abstract:This paper investigates the topology and control strategies of AC/DC green hydrogen power supplies， aiming to improve their adaptability to renewable energy fluctuations and conversion efficiency. Firstly， mainstream converter topologies including voltage-source， current-source and multi-level types are systematically reviewed， and their corresponding control methods are discussed in depth. Secondly， further analysis is carried out on the nonlinear characteristics of electrolyzers， as well as the requirements of low ripple and fast dynamic response. Key control strategies are compared， including direct current control， direct power control， sliding mode control， one-cycle control， model predictive control and linear active disturbance rejection control， with their performance features and applicable scenarios analyzed. Finally， matching principles between topologies and control strategies are proposed according to different power levels and application scenarios. This work provides a theoretical basis and engineering reference for optimal power supply selection and control strategy design in high-proportion renewable energy hydrogen production systems.
