Abstract

PURPOSE:To enable use of a switching element having low withstand voltage by connecting the neutral point of a motor always to a neutral point of a power source when the motor is used as a load, thereby forming an output having less harmonic wave content rate. CONSTITUTION:The mutual connecting points of DC power sources 10, 11 operates as a function of a neutral point 0 of a power source, and this point 0 is connected to the neutral point of a load such as a motor or the like via output terminals A, C. The power sources 10, 11 form a series power source as a hole, and supplies power from terminals P, N. a smoothing capacitor 12 and 2-phase switching circuit 13 are connected between the terminals P and N. In this switching circuit 13, transistors Tr51, Tr52 and Tr61, Tr62 are connected in series with each other, and both ends of the series connection are respectively connected to series power terminals P, N. The mutual connecting points of the series connection becomes output terminals B, D. Further, transistors Tr53, Tr54 and Tr63, Tr64 are connected between the output terminals A, B and C, D.
