ABSTRACT:
A power supply circuit for various actuators includes control lines associated with the actuators that receive power from a single voltage increasing circuit. The power supply circuit supplies power to the control lines by splitting or dividing power from a voltage increasing circuit, which is configured to increase an on-board power source voltage. Power is supplied to loads by driving circuits. The loads are individually driven by activating switches. An auxiliary control line is connected to one of the control lines so that auxiliary voltage is able to be supplied or applied. A voltage-holding circuit is provided in connection with the other control line to eliminate influence associated with the activation of one control line with respect to the other control line.
