Fuel cell (FC)/lithium-ion battery hybrid power system (HPS) gradually becomes a powerful energy source in the future. This paper presents a digital boost converter for FC current regulation in the HPS with a dual-battery energy storage unit (ESU). The digital boost converter regulates the FC current in order to control the FC power generation. Simulations have been conducted in PSIM environment,...
This paper presents a new hybrid power system with battery depth-of-discharge (DOD) management for extending battery cycle life and system service time. The proposed power system consists of a power management system, a dual-battery unit, a fuel cell (FC) stack, and two dc/dc unidirectional power converters. The dual-battery unit serves as the primary power source, while the FC stack serves as the...
