<p>The invention discloses an alternative current (AC) generator for vehicle in response to a command from an engine control device under the control of a switching control unit, an operation state is switching between a full-generation operation state for enabling all coils to generate AC and a partial generation operation state for enabling partial coil to generate the AC; when a rotary speed of an external rotor is raised, the full-generation state is switched into the partial generation state under accelerated time switching rotary speed; when the rotary speed of the external rotor is reduced, the partial generation state is switching into the full-generation state in a decelerated time conversion rotary speed; and the accelerated time switching rotary speed is more than the decelerated time conversion rotary speed.</p> |
