PROBLEM TO BE SOLVED: To provide a power converter which is capable of averaging the temperature of an apparatus, while minimizing the switching frequency of the apparatus and outputting an arbitrary output voltage, while correcting the unbalance between the voltage of positive and negative capacitors. SOLUTION: This converter includes an output voltage vector control part 27, consisting of an angle difference maximum vector detection part 27 computing the angle of a difference integrating vector outputted by a difference vector integrating part 22 to a difference vector outputted by a second difference vector computing part 21, and an output vector selection part 25 selecting, as an output voltage vector Vo, a voltage vector which can be output corresponding to an output voltage vector selection signal, out of inputted voltage vectors which can be output. |
