Abstract
A power converter apparatus, including a DC power source, a semiconductor stack, connected to the DC power source in parallel, having a plurality of semiconductor devices and a cooler for refrigerating the semiconductor devices, the semiconductor devices and the cooler are stacked and pressured to each other, and a snubber circuit, connected to the DC power source in parallel, having a serial circuit of a capacitor and a diode, and a resistor connected in parallel to the diode, one terminal of the capacitor is disposed adjacent to the semiconductor stack so that magnetic flux generated by current flowing in the terminal cancels magnetic flux caused by current flowing in the semiconductor stack.
