<p>An electric power steering apparatus causes a bridge circuit and a driver circuit to control normal and reverse rotation operations of a motor. The bridge circuit is constituted by transistors. The driver circuit is connected to a power source and also is connected to the bridge circuit so as to drive the bridge circuit. A diode is inserted between the power source and the bridge circuit, and the polarities of the diode are set such that a voltage at the bridge circuit is lower than that at the driver circuit.</p> |
