Abstract
Unit converters each comprises a capacitor, a switching element having a flat surface on one side, a P-pole connection conductor where a second terminal hole at one end for fixing an electrode corresponding to a P-pole of the switching element and a first terminal hole at the other end for fixing a terminal of the capacitor are formed, and an N-pole connection conductor where a second terminal hole at one end for fixing an electrode corresponding to a N-pole of the switching element and a first terminal hole at the other end for fixing a terminal of the capacitor are formed. The unit-converters each including the connection conductors arranged to overlap in the thickness direction with their insulation maintained make the cooling surfaces of the switching elements be opposed to each other with a cooling device therebetween.
