Abstract:
A generating apparatus for feeding a DC current to a load including a voltage accumulating means, comprising:a magneto which includes a rotor having a magnet field and a stator including generating coils;a rectifying/switch circuit including a diode bridge full-wave rectifying circuit and a switch circuit;said diode bridge full-wave rectifying circuit being constituted by diodes of 2n (n: an integer of 2 or more) in number bridge-connected to each other and operable to feed an output of said magneto to said load while rectifying the output;said switch circuit being constituted by switch elements of 2n in number respectively connected to said diodes by reverse parallel connection, to thereby be bridge-connected to each other; anda switch control unit for setting both a drive period and a non-drive period of each of said switch elements of said switch circuit and feeding each of said switch elements with a drive signal for keeping each of said switch elements turned on during said set drive period, resulting in an AC control voltage having a predetermined phase angle with respect to a voltage induced across said generating coils during non-loading being applied from said voltage accumulating means through said switch circuit to said generating coils;said switch control unit including a phase angle control means for varying a phase of said control voltage with respect to the voltage induced on said generating coils during no-load from a delay phase to an advance phase so that specific characteristics of said magneto may be controlled as desired.
