Abstract
A control circuit for controlling a plurality of power supply modules connected in parallel to provide power to a single load. The control module first converts first analog data corresponding to a voltage level which is applied to the load. The control module then compares the voltage level to a predetermined voltage level and computes a voltage deviation between the predetermined voltage level and the voltage applied to the load. The control module then computes whether the voltage deviation is within a proper limit or not. The control module then sends a pulse width data signal corresponding to the voltage deviation to the power supply modules in order to control the amount of power each module supplies to the load.
