Abstract

A generator system uses compressed air as a power source and utilizes an electromagnetic auxiliary power unit. The generator system includes an engine (1), a multiple-column power distributor (2), a generator system (4), a controller system (6), an intake speed control valve (23), a high pressure gas tank (13), a constant pressure tank (16), an electronic control unit ECO (29), an electromagnetic auxiliary power unit (1000), a power distributor (1100) and an end gas recycle loop. The end gas recycle loop includes an air compressor (7), a condenser (11), an end gas recycle tank (9), an electro-drive turbine unidirectional suction pump (19) and an end gas muffler (22).
