Title:
交流電動機用速度制御機の直流バス上の電圧管理方法およびシステム
Document Type and Number:
Japanese Patent JP4912688
Kind Code:
B2
Abstract:
The method involves comparing a voltage value measured on a DC bus with a determined limiting value by a comparator (10). Slope of an internal ramp (R) is forced to zero value when the voltage value is higher than the limiting value, in order to confer a constant frequency to a stator of an AC motor. The slope value is progressively increased when the voltage value is lower than the limiting value. An independent claim is also included for a system of controlling voltage on a DC bus of a speed controller for an AC motor connected to a current distribution network.
