Abstract

PURPOSE: To supply output electric current which does not contain higher harmonic wave and is near sine wave, by putting on inverter current, using a transformer which forms revolving magnetic field in the output side of unit inverter.
CONSTITUTION: Direct current source 3,3' are connected to unit inverters 2,2' through reactors 1,1', alternating current which contains higher harmonic wave is supplied to the primary windings 61,62 of a transformer 6 by this output, revolving magnetic field is induced, then, voltage is induced in output winding 64, and electric current is supplied to load 5. therefore, electric current phase of unit inverters 2,2' is made to be postponed as 30°, coresponding to this, primary windings 61,62 of the transformer 6 is made to be postponed in the space as 30°, then 5 times and 7 times harmonic wave component in revolving magnetic field which is obtained in the primary windings 61,62 are mutually denied, and they are not appeared in the output winding 64. Therefore, electric current which is supplied to load 5 can be made as sine wave which does not contain higher harmonic wave under 13 times.
