Abstract
A multiple power supplies balance system includes a plurality of power supply circuits on a circuit board each having a power output route. Each power supply circuit includes a power supply feedback unit which has a reference level terminal to determine output potential of the power supply circuit. The circuit board also has an output route electrically connected to the power output route to converge current sending to a load. Thus the circuit board contains multiple sets of power supply circuits coupled in parallel. The circuit board also has a proportion distribution circuit to correct output variations of each power supply circuit. The proportion distribution circuit includes a variable impedance element which is electrically connected to the reference level terminals and controllable to proportionally change equivalent impedance connected to each reference level terminal, thus change proportionally output potential of each power supply circuit.
