The three power generation output modes can provide the same or different combinations of various output selections of the generated power and the selection of various types of generated voltages such as alternating current and direct current, high voltage and low voltage. The novel multi-combination power generation output provides a new solution for the intellectualization and higher efficiency, energy conservation, environmental protection and multiple purposes of equipment for providing rotary power for the generator, such as an internal combustion engine, and also provides a new basic condition for the application of multiple purposes of the generator.
