PROBLEM TO BE SOLVED: To provide a power converter which swiftly suppresses the oscillation of a direct current circuit. SOLUTION: The power converter comprises a direct-current voltage. detecting means for detecting an output voltage; a direct-current voltage control means which calculates a direct current command value from the difference between a direct-current voltage command value and a direct-current voltage detection value; a direct-current detecting means which detects a direct-current flowing out to other power converters; a direct current constant multiplying means which multiplies a direct-current detection value by an integer; a direct current differentiating means which multiplies the differentiation value of the direct-current detection value by an integer; an adding means which adds the output of the direct current differentiating means and the output of the direct current constant multiplying means; and a subtracting means which subtracts the output value of the adding means from the output of the direct-current voltage control means and the direct current command value to create the direct current command value.
