ABSTRACT:
A current control type converter has a converter section and a control section that includes three controllers. A first controller calculates and outputs an active current instruction value by proportional-plus-integral control to perform proportional integration of a deviation between the value of a DC voltage outputted from the converter section and a DC voltage instruction value. A second controller calculates and outputs an active voltage correction value by proportional-plus-integral control to perform proportional integration of a deviation between the active current instruction value from the first controller and the value of an active current inputted to the converter section. A third controller calculates and outputs a reactive voltage correction value by proportional-plus-integral control to perform proportional integration of a deviation between the value of a reactive current inputted to the converter section and a reactive current instruction value.
