ABSTRACT:
A DC-AC converter for supplying power from a DC power source to a load that is also supplied power by an AC power source. The DC power source is applied to the load with alternating polarity at the frequency and phase of the AC power source. Transients are reduced by limiting the application of the DC power source to the load to less than the duration of each half cycle of the AC power source.
