PURPOSE:To provide a power supply for internal-combustion engine in which the starting performance of the engine can be enhanced by lowering the r.p.m. for operating a fuel pump stably. CONSTITUTION:A power generation coil Wp for driving a plurality of loads is provided commonly for a fuel pump and general loads in a magnet generator. Output voltage from the power generation coil Wp is fed through a first power supply circuit, having a boosting function and a rectifying function, to a fuel pump 11 and through a switch means 14 to a general load 13, e.g. a lighting load 15. A switch control means 17 turns the switch means 14 OFF when the pump driving voltage Vp being applied to the fuel pump 11 is lower than a set level, otherwise turns the switch means 14 ON. |
