  • Parallel power supply system and control method thereof
    Publication number: 20040201283
    Abstract: A parallel power system provides virtual impedance so that the parallel-connected power supplies can couple each other directly and the parallel-connected power supplies have the same real power output by the adjustment of output voltage references. Furthermore, the virtual impedance is greater than an intrinsic impedance of the power supply and thus the virtual impedance is dominant impedance. Therefore, the parallel-connected power supplies can couple each other directly without linking inductors.
