Title:
CONTROLLER FOR INDUCTION GENERATOR
Document Type and Number:
Japanese Patent JPH05134773
Kind Code:
A
Abstract:
PURPOSE:To eliminate the need for considering the problem of a rotary detector, to reduce size and cost and to improve responsibility and stability by means of high speed current control. CONSTITUTION:A current comparison circuit 14 compares the command value from a current control circuit 13 with the detected value from a current detector 8 and outputs a logic level signal. A commutation control circuit 16 outputs a voltage synchronization signal and a voltage reference phase signal based on the logic level signal. A PWM control circuit 19 performs the PWM control of a converter 3 based on the logic level signal, voltage synchronozation signal and voltage reference phase signal. The rotation of an induction generator 2 is changed corresponding to the change of the changing ratio of its output current. Thus, the frequency of the voltage synchronization signal to be outputted from the commutation control circuit 16 is also changed corresponding to the rotation speed.
