<P>PROBLEM TO BE SOLVED: To provide a power converter which can increase the capacity of a system without increasing the capacity of a fuel cell power supply. <P>SOLUTION: This power converter comprises a U-shape single-phase inverter 10u, a V-phase single-phase inverter 10v, a W-phase single-phase inverter 10w, and a controller 3 which controls drivers 4u, 4v, and 4w of the respective inverters. A U-shape fuel cell power supply, a V-phase fuel cell power supply, and a W-phase fuel cell power supply comprise fuel cells 1au and 1bu, fuel cells 1av and 1bv, and fuel cells 1aw and 1bw respectively. A U-shape power conversion unit, a V-phase power conversion unit, and W-phase power conversion unit comprises transistors 2au and 2bu, transistors 2av and 2bv, and transistors 2aw and 2bw respectively. Respective one side ends of a U-phase winding, a V-phase winding, and a W-phase winding of a star-connected three-phase AC motor 6 are connected to a U-phase output terminal 5u, a V-phase output terminal 5v, and a W-phase output terminal 5w respectively. <P>COPYRIGHT: (C)2003,JPO |
