Abstract
In a power converter apparatus, a first power converter circuit is configured of first power semiconductor devices, and a second power converter circuit is connected in parallel to the first power converter circuit, and is configured of second power semiconductor devices. A control circuit generates a control signal for controlling each power semiconductor device of the first and second power converter circuits. A timing control signal generator circuit compares a first amount of current flowing through the first power semiconductor devices with a second amount of current flowing through the second power semiconductor devices, and generate a timing control signal for controlling a timing of a rise or a fall of each of the control signals inputted to the first and second power converter circuits, based on a comparison result. A timing correction circuit controls the control signals to correct the timing of the rise or the fall thereof.
