Instantaneous voltage-drop compensation circuit for power conversion apparatus, has control pulse signal generator for generating control pulse signals for power converter based on three-phase control signals

摘要

The circuit has a subtracter (27) generating a deviation signal from input current command signals and two-phase current signals. An input current controller (28) generates input current control signals based on the deviation signal. An adder (29) adds two-phase voltage signals to the input current control signals. A two-phase to three-phase converter (19) converts the input current control signals to three-phase control signals. A control pulse signal generator (34) generates a control pulse signals for a power converter based on the three-phase control signals. Independent claims are also included for the following: (1) an instantaneous voltage-drop compensation method (2) a computer readable medium storing a program for making a computer to perform an instantaneous voltage-drop compensation method.
