Abstract
Abstract This emergency standby power system includes a battery which is constantly charged whenever the normal AC source is functioning. The battery supplies power to an inverter which is coupled to one of the output terminals and which is synchronized by induced voltages applied to the inverter input in response to the vibrations of a vibrating magnetic element. The vibrating element responds to the AC source when it is functioning and to an auxiliary winding connected to the output of the inverter when the AC source is not functioning. When the AC source is not functioning, a turbine-driven DC generator applies current to power the inverter.
