Abstract
A secondary power system eliminates the need for an automatic transfer switch and permits simultaneous supply from different sources. Primary power is rectified and connected to a DC bus, an AC generator has its output rectified and connected to the DC bus, and a storage battery is also connected to the DC bus. Current on the DC bus is inverted to AC to provide an uninterrupted power supply. The system is connected to a household electrical system by a power distribution panel which can be installed in a home prior to the secondary power system and can facilitate installation of the secondary system. The distribution panel can selectively bypass the secondary system and can disconnect non-vital loads when primary power is not available. The generator is powered by an engine using gasoline, natural gas or water, which can also power other systems, such as air conditioning, with exhaust heat or rotary motion.
