Abstract : A 50 ampere power processor for shelter mounted hydrocarbon-air fuel cell power systems is described. The processor converts raw fuel cell power to the precise, high quality power required by military communications-electronic equipment. It is characterized by high efficiency (greater than 90%), high reliability (10,000 hours MTBF), and light weight, accomplished through the use of advanced high frequency, current controlled, switch modulation techniques. Automatic protection of the fuel cell against overloads, reverse current, and undervoltage operation is provided. A unique function of the processor is that it optimally loads the fuel cell to aid in system bootstrapping for faster start-up. Current limiting allows parallel operation when higher power levels are required and provides a battery charging capability. Interface compatibility with the fuel cell, battery and load, and ancillary items are also discussed. (Author)
