Abstract
A power converter includes: a power converter main circuit that includes semiconductor switching elements; gate drive circuits driving the semiconductor switching elements, respectively; and one or a plurality of impedance element groups connected between at least one pair of the gate drive circuits. At least one of the gate drive circuits includes a detector that detects a voltage across the impedance element group, and changes the driving speed of the semiconductor switching elements in accordance with an output of the detector.
