Abstract

PURPOSE:To eliminate fluctuation of both output voltages even if a load size or a engine speed changes by providing a rectifying means for converting a high AC voltage to a high DC voltage and a DC-DC converter with a constant voltage output function for converting the high DC voltage to a low DC voltage. CONSTITUTION:A high voltage AC output with an effective value of 100V which is generated by a high voltage coil 1 is rectified by a high-voltage rectifier 2, is smoothed by a smoothing capacitor 3, then a high-voltage DC power at 140V is supplied to a high-voltage-drive electrical device 4. On the other hand, one part of the high-voltage DC power is converted into a low-voltage DC power of 12V through a DC-DC converter 5 with a constant-voltage output function and is supplied to a battery 6 or a DC low-voltage drive electrical device 7. At this time, a regulator 9 detects a high DC voltage value and allows a field current IF controlled to be constant to flow to a field coil 8.
