摘要： Three or more circuits, in which series-connected low-voltage and high-voltage side switches including MOSFETs including parasitic diodes are connected across positive and negative terminals of each of smoothing capacitors, are connected in series. One of elementary series circuits, each including a capacitor and an inductor, is disposed between any adjacent two of the circuits with the elementary series circuits set to have the same period of resonance. The MOSFETs of rectifier circuits are brought into an ON state simultaneously with the MOSFETs of a driving inverter circuit and brought into an OFF state earlier than the MOSFETs of the driving inverter circuit by a period of time not exceeding a time period equal to (period of resonance)/2. A resonance phenomenon of the capacitor and the inductor is used and conduction loss in the rectifier circuits is reduced in DC/DC power conversion performed through charging and discharging operation of the capacitor.

摘要： 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.
