Vehicular generator-motor control apparatus
First Claim
1. A vehicular generator-motor control apparatus wherein a winding field type salient-pole generator-motor for a vehicle is subjected to a conduction control by a DC-AC converter, comprising:
- detection means for detecting a position of a rotor; and
means for energizing a stator of the vehicular winding field type salient-pole generator-motor by applying rectangular wave voltages to the winding field type salient-pole generator-motor at conduction start angles of respective phases of the stator, wherein the conduction start angles are shifted by a predetermined angle relative to the position of the rotor detected by the detection means, and the conduction start angles of the respective phases change substantially continuously in accordance with an input voltage of the DC-AC converter and a revolution speed of the winding field type salient-pole generator-motor.
