Abstract
A voltage source capable of coupling in parallel to at least one second voltage source, the second voltage source having an AC waveform to power at least one load. The voltage source includes a power supply and a controller. The controller is associated with the power supply. The controller includes an AC waveform generator which is capable of providing a waveform to an output, a sensor for sensing the AC waveform produced by the second voltage source and a member for phase shifting the AC waveform to synchronize same to the AC waveform of the second voltage source.
