PURPOSE:To reduce influence of mutual interference of a plurality of inverters as much as possible. CONSTITUTION:Control circuits of a plurality of inverters are integrally formed as a control circuit section F. Main circuit sections K1, K2, the section F and a power supply section G are mounted one printed board 6 in a block manner. Power supply patterns e1, e2 or ground patterns g1, g2 are so formed as to from isolation among the sections K1, K2, the sections F, and G. |
