ABSTRACT:
A method and apparatus for reducing imbalances among the outputs of a plurality of driver devices connected in a parallel configuration to drive a common load. One driver is designated as the master, and suitable servo circuitry is provided to each of the other slave drivers, each servo being operative to force the output of its associated slave driver to accurately track the output of the designated master driver. The servo circuitry may be disposed to equalize either the output voltages or output currents of the several drivers to ensure load balancing among the drivers, to reduce cross-conduction currents and attendant power wastage and improve dynamic performance. The plurality of drivers may either operate in an open-loop configuration, or be enclosed within an overall negative feedback loop under the control of a separate controller that itself may be an amplifier.
