UIC-2006-029 – A Novel, Power-Management Control for the Fuel Cell Power Conditioning System

This invention is a new Power Management Control for the power conditioning system. This system provides a methodology to alleviate load transient mitigation so as to improve the steady state energy efficiency of a fuel cell power conditioner. It consists of a topological control system that is a distributed converter. This eliminates the need for two separate converters, reducing costs. Additionally, there is a fuel cell maximum efficiency tracking control system, which allows the cell to attain optimal stack efficiency at different output power demand levels by incorporating the fuel utilization of the stack as a reference parameter. The final part of the system is a zero ripple boost converter, which minimizes the switching ripple and inverter ripple, thereby enhancing the overall efficiency of the system.
