PROBLEM TO BE SOLVED: To provide an electrical load driving apparatus which can, if any of a plurality of electrical loads gets out of control, drive the other electrical loads. SOLUTION: A controller 30 determines whether an alternating-current motor M1 is uncontrollable and whether a power supply B is fully charged based on direct-current voltage Vb from a voltage sensor 10A, temperature Tb from a temperature sensor 10B, current BCRT from a current sensor 11, motor current MCRT from a current sensor 24, and motor number of revolutions MRN from an external ECU. If the alternating-current motor M1 is uncontrollable and the direct-current power supply B is fully charged, the controller 30 outputs a stop signal STP to a boosting converter 12 for stopping the boosting converter 12. Also, the controller 30 outputs a maintaining signal MTN to system relays SR1 and SR2 for keeping on the system relays SR1 and SR2. COPYRIGHT: (C)2004,JPO |
