Abstract

PURPOSE:To reduce the harmonic wave component content of an AC output from the inverter by connecting once a neutral point of power source to the output terminal when connecting the output terminal to the other DC power source terminal after connecting it to the one DC power source terminal. CONSTITUTION:Switching elements S11-S34 are controlled on or off, thereby producing polyphase AC voltages between the terminals U, V, W and neutral point O. The elements S11 and S14 and, S12 and S13 have the relationship that when one is turned on the other is turned off. When the elements S14, S13 are on and the elements S11, S12 are off, the output VV-O (between the terminal V and O) is zero. When the elements S11, S13 are on and the elements S14, S12 are off, the output VU-O (between the terminal U and O) becomes the potential of the terminal P. Then, when the VU-O is zero and the elements S14, S12 are on and the elements S11, S13 are off, the VU-O becomes the potential of the terminal N. Since the output voltage VU-O(VV-O, VW-O) becomes the zero potential of the neutral point, the harmonic wave component content can be reduced.
