发明名称 ELECTRICAL POWER SYSTEM
摘要 <P>PROBLEM TO BE SOLVED: To provide an electrical power system capable of preventing power supply to a load from stopping by stabilizing a bus voltage even when a power converter that controls a bus voltage stops. <P>SOLUTION: The electrical power system includes a first power converter 1 for controlling an AC voltage of a bus bar 100 and a second power converter 2 for controlling an alternating current supplied to the bus bar 100 and supplies, to the bus bar, an alternating current converted from a direct current. Each of the first and second power converters 1, 2 has a bus bar voltage control function and an output current control function and can operate in either of a voltage control mode or a current control mode. <P>COPYRIGHT: (C)2012,JPO&INPIT
