Abstract: An AC induction motor is controlled by dynamically matching energy use by the motor to the load on the motor. First and second SCRs are connected in parallel with each other in opposing polarities for each phase of the applied AC voltage. A trigger generator couples trigger control signals to the respective gates of the SCRs responsive to the timing of sensed zero-crossing events of the AC voltage and current in the respective phase applied to the motor winding. The first and second SCRs are alternately triggered into a conductive state during each alternation of the applied AC voltage and are alternately inhibited from the conductive state for an interval in time proportional to a measured difference in time between the AC voltage zero-crossing and the corresponding AC current zero-crossing as determined by comparing the time difference between successive first and second interrupts corresponding to the zero-crossing events with a continuously running time base.
