Abstract: A servo power amplifier for driving multiple DC motors (10, 12) employs a load equalization circuit (36) which allows reduction of the overall number of circuit components required to drive the motors. The load equalization circuit is coupled in parallel with each of the motor drive circuits (14, 16) across the power source (46, 48) and controls an inductive load (84) which temporarily stores energy that is returned to the power source from the motors. The equalization circuit is pulse width modulated in accordance with a control signal which is derived by sensing the current flowing through the inductive load and using a sensing circuit (44) to determine the difference in the magnitude of the positive and negative voltages supplied by the power source. The equalization control circuit and the motor drive circuits are each T-configured and employ no more than two switching elements for controlling current flow.
