Abstract
To provide a power converter which can distribute heat generation of the switching devices with good accuracy, even when the maximum heating phase of the positive electrode side and the maximum heating phase of the negative electrode side are different phases, and even when the maximum heating phase of the positive electrode side and the maximum heating phase of the negative electrode side changes before and after combining the offset voltage. The power converter calculates the offset voltage that makes the positive electrode side maximum heating evaluation value and the negative electrode side maximum heating evaluation value coincide with each other, in a state of controlling on/off the switching devices based on the combined AC voltage commands of the offset voltage.
