<P>PROBLEM TO BE SOLVED: To provide a control device of a high voltage inverter for automatically and accurately setting up a coupling position of neutral point of the high voltage inverter. <P>SOLUTION: A master controller determines information of a neutral point preset to itself (S400), and perform communication with a cell controller disposed at each of a plurality of U phase unit cells, a plurality of V phase unit cells, and a plurality of W phase unit cells to receive information from each cell (S406), determines the neutral point information preset in each cell controller (S408), detects a cell controller set up with neutral point information different from that of the master controller to generate a command for correcting the neutral point information of the detected relevant cell controller to the neutral point information set up in the master controller (S410), and then operates the high voltage inverter (S412). <P>COPYRIGHT: (C)2011,JPO&INPIT |
