Abstract :
This paper discusses the principle and electrical characteristics of the fuel cell, designs an innovative hybrid power system, and proposes a new DC-DC converter scheme to combine the fuel cell with the storage system. An effective converter scheme for fuel cell is obtained by analyzing the high efficient topology as well as the phase shifted PWM. Through comparing several different control modes of converters, a 75 kW prototype system based on DSP is constructed, moreover, which steady state operating characteristics are illustrated and discussed in detail. At last, experimental results are also shown to verify the proposed scheme.
