To provide a generator which can perform a self-help operation over a long time in many fields.

A mechanical relation between a magnet for power generation and a power generation element is eliminated. A single rotary machine 1 is devised to operate a plurality of power generation elements and supplies and outputs electric power. A charge adjusting apparatus 9 performs efficient charging, and loss compensation power supply which occurs in the future is installed, and long self-help operation can also be performed.
