Abstract
An electric equipment drive control system for controlling the drive of the electric equipment, wherein the drive control equipment includes a pulse signal generator for generating a pulse signal having the pulse signal corresponding to the voltage value at the power source, a microprocessor circuit which acts synchronously with the pulse signal outputted from the pulse signal generator and which executes a program prepared with a prerequisite that the voltage at the power source is a predetermined voltage, and a drive circuit for turning on and off the connection of each circuit in the electric equipment and the power source. The pulse signal generator increases the frequency of the pulse signal when the power voltage is higher than the predetermined voltage, and decreases the frequency of the pulse signal when the power voltage is lower than the predetermined voltage.
