A method for controlling a plurality of electronic switches employed to connect an alternating current voltage source with a motor. The method comprises the steps of generating a signal, directing the signal to each of a series of output lines in sequence, regularly repeating the directing step, conducting the signal from the output lines to the electronic switches to actuate the electronic switches, and continuously resynchronizing the directing of the signal with the voltage cycle of the voltage source.
