Abstract
A voltage controller has a control circuit and a heat radiating member attached to the circuit. The circuit controls a voltage of electric power generated in an alternator of a vehicle while generating heat. The member has a first surface and a second surface. The second surface of the member is formed in a smooth shape having no protrusions or hollows. A cooling wind flows on the second surface. The member receives the heat from the control circuit through the first surface and radiates the heat from the second surface to the wind.
