Control of isolated hydrogen generation power supply for the DC power grid

Abstract The utilization of water electrolysis hydrogen in DC power grids can effectively improve the absorption and renewable energy, production supply is a key equipment. This article designs an isolated supply, which adopts bidirectional active H-bridge topology modular design. In process production, use constant current voltage control, development control strategies for but input ripple electrolytic cell heavy, so driving pulse interleaving phase shift between modules adopted. achieve with small ripple, feasibility effectiveness preparation strategy have been verified through simulation experiments.
