ABSTRACT:
A method and electrical circuit for dynamic reconfiguration of a DC-to-AC inverter comprising first and second power rails where each the rails has a power source. The method comprises monitoring the first and second power rails for short-circuit failure; and upon failure of one of the power rails, disconnecting the failed power rail from its power source.
