摘要 |
An instantaneous voltage-drop compensation circuit including: a first voltage detector detecting three-phase voltages to be input to a power converter converting three-phase AC to DC based on control pulse signals, and outputting three-phase voltage signals; a first three-phase to two-phase converter converting the detected signals to two-phase voltage signals; a first current detector detecting three-phase currents to be input to the power converter and outputting three-phase current signals; a second three-phase to two-phase converter converting the detected current signals to two-phase current signals; a first subtracter generating a first deviation signal from input current command signals and the two-phase current signals; an input current controller generating input current control signals based on the first deviation signal; and a first adder adding the two-phase voltage signals to the input current control signals, to generate control pulse signals for the power converter.
