<P>PROBLEM TO BE SOLVED: To reduce the unevenness of current flowing to each semiconductor element and to stabilize the potential of a negative side conductor when the positive side conductor and the negative side conductor of a main circuit conductor are insulated, laminated, a plurality of the semiconductor elements are electrically connected to the main circuit conductor, and a plurality of semiconductor power modules for constituting a bridge circuit are connected in parallel. <P>SOLUTION: In a power converter, a means for improving the unevenness of the current is provided only at a positive side capacitor bus bar at the capacitor bus bar using parallel flat plate-like conductor, and the negative side capacitor bus bar is formed as one flat plate. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
