Abstract: A capacitance based reactive power balancing current limited power supply (RPBCLPS) for driving floating DC loads utilizes capacitive reactance to limit current being supplied to a load, rather than inductance. A capacitor transfers charge from an AC current input to a DC load. A fuse electrically protects the capacitor from high frequency current harmonics. A diode clamp electrically protects the capacitor from voltage spikes. A rectifier converts the AC current input into DC current for driving the DC load. The reactive power balancing current limited power supply can be incorporated as a key component into reactive power balancing electrical power distribution systems. Such systems can comprise a grid configuration structured to distribute the AC electrical power from a utility source to a plurality of DC loads. Further, the DC loads can be cooperatively located to provide functional distributed capacitance throughout a substantial portion of the grid.
