A protection operation control part switches a gate signal interruption switch for protection of power elements to a gate signal interruption side, and invalidates a switching signal from a hybrid control unit to place transistors into a nonconducting operation. A motor current signal from a motor current detector is converted into a current value by a motor current calculation unit, and is inputted to a short-circuit abnormality detection unit through a motor control arithmetic part, and a short-circuit abnormality is detected. At a time of detecting the short-circuit abnormality, an internal combustion engine operation instruction unit gives an instruction to an internal combustion engine control unit so as to limit output of an internal combustion engine, and releases a conduction state of an abnormal motor current.
A vehicular power control apparatus for performing power control of a hybrid vehicle using output of an internal combustion engine and output of an AC motor as sources of power, comprising:
