[57] ABSTRACT

This invention provides a cogeneration system formed compactly and provided with a plurality of generators, wherein a plurality of miniaturized generators are coupled to a flywheel provided in an engine. In this cogeneration system, a toothed endless belt is meshed with a toothed portion formed on an outer circumference of the flywheel provided in an engine, and electric power is generated by driving a plurality of generators by the toothed endless belt via speedup gears. The electric power generated by the generators is synthesized and then transformed by a transformer, and the resultant electric power is consumed by a load via a rectifying diode and an inverter.
