Abstract
A power conversion apparatus includes a current component control section which outputs q axis and d axis negative-sequence components and q axis and d axis positive-sequence components based on a detected current value or a voltage value, a current component control which compares a current component with the current instruction value from an instruction value generator and outputs to an adder/subtractor the result, a converter converting a control signal output from the adder/subtractor into three-phase components, and an adder adding these three-phase components to respective phases and outputting the result to a power conversion section.
