Abstract

PURPOSE:To suppress the rapid change of the divided voltage to supply a stable voltage, by reducing the resistance value of the resistance, which is connected in series to the capacitor type voltage dividing circuit which divides the voltage of the lithium battery, when the heavy-load device is not driven. CONSTITUTION:Resistance circuit 10 is connected in series to 1/2 voltage dividing circuit 8 consisting of capacitors 8a and 8b. Motor 6 is driven by the pulse of 1Hz having the width of 7.8msec from motor driving circuit 5. Resistance control circuit 11 generates a resistance control signal, which is wider by the half pulse width, synchronously with the motor driving signal and inputs this signal to the gate of the N type MOSFET of resistance circuit 10 to raise the resistance value of N type MOSFET.
