Abstract
An automatic transfer switch for a power system receiving multiple alternating current sources and delivering multiple alternating current output is described. A transfer switch control circuit can sense a power loss in one or both AC sources. Each power supply can deliver current to drive a load but, if one of the power supplies fails, the other can supply power to drive both loads.
