Document Type and Number:

WIPO Patent Application WO/2013/105238

Kind Code:

A1

Abstract:

An engine control device is provided with: a three-phase bridge circuit of which one end is connected to one end of a first load while the other end is connected to the ground and which rectifies the alternating-current power supplied from a motor generator or motor-drives the motor generator; a DC-DC converter connected between one end of the three-phase bridge circuit and the other end of a control switch; a diode of which the anode is connected to a battery connection terminal and the cathode is connected to the other end of the control switch; a voltage detection circuit for detecting the voltage of the battery connection terminal; a first switch element connected between the other end of a coil and the ground; a second switch connected between the other end of the first load and the ground; and a control circuit to which a direct-current power supplied to one end of the control switch is supplied and which controls the three-phase bridge circuit and the first and second switch elements.
