An internal combustion engine electrical system is disclosed which is adapted to use an internal combustion engine as a driving source. The generating system is constructed in a manner such that the output of an A.C. generator driven by the engine is rectified by a rectifier circuit, and the output of the rectifier circuit is inverted into an A.C. output by an inverter circuit adapted to use, a commutation command signal, the output of an oscillator circuit which generates a signal of a constant frequency.
