Operation

In this example, power is available from the normal and bypass sources, as well as from the battery. Notice that the switching devices are all closed except for the bypass switch at the top. The load is operating on conditioned power from the inverter. The battery is being charged by the rectifier. The static switch is operative and ready to respond to momentary demands for overload current.
