  • Electrical load controller and vehicle air conditioner using the same
    Patent number: 6690560
    Abstract: In an electrical load controller, a thermal fuse is blown at an abnormal heating of an electrical load, so that an electrical circuit of the electrical load is disconnected. The controller controls a work amount of the electrical load by intermittently controlling electrical power to be supplied thereto. The power supply to the electrical load is intermittently stopped even when the work amount of the electrical load is controlled at a maximum amount. Therefore, an arc, generated when the thermal fuse is blown, disappears while the power supply is stopped, so that the thermal fuse can be accurately operated.
