ABSTRACT:
An exciting current controlling transistor or a high-side switch or low-side switch of a three-phase full-wave rectifier for an on-vehicle a.c. generator is formed of a MOS power transistor made of a monocrystalline SiC semiconductor. Further, at high output condition time, for example, a state wherein the generator is in a condition of low temperature and a battery capacity is decreased, a controller suppresses the duty ratio of the exciting current controlling transistor to thereby limit a field coil exciting current. As a result, an increase in cross-sectional area of the electric wire or a temporary rapid increase in torque of the engine load is avoided. Also, by limiting the rate of increase in the duty ratio, the controller prevents a fall in the engine speed.
