Abstract :
High power DC/DC converter has become the essential part of the distributed power system in fuel cell powered electric vehicles and stationary power systems. This paper proposes a topology of high power dual-phase boost DC/DC converter for fuel cell power supply. The principle of the converter operating in BOOST mode are analyzed thoroughly. A 150 KW converter was designed. The converter was adopted DSP-based fully digital dual-loop control. The efficiency of the converter is over 97%, the experimental results realized perfect effect
