Abstract
A generating apparatus for feeding a current to a battery using a magneto as a power supply is disclosed which is capable of varying a magnetic field acting on generating coils to widely control characteristics of the magneto. A rectifying/switch circuit is arranged between the magneto and a load, which incorporates the battery. The rectifying/switch circuit includes diodes and switch elements. The diodes are 2n (n.gtoreq.2) in number and are bridge-connected to each other. The switch elements are connected to the diodes by reverse parallel connection. A switch control unit applies an AC control voltage of a predetermined phase from the battery through the rectifying/switch circuit to the generating coils, so that a phase of the AC control voltage may be varied to widely vary characteristics of the magneto.
