Abstract

PURPOSE:To control higher harmonics by inserting a reactor having a plurality of windings between a polyphase multiple PWM inverter and a load so that there exists a given phase relation between carrier signals of PWM signals. CONSTITUTION:A three-phase double inverter 2 composed of two sets of three- phase inverters supplies a three-phase double winding motor 4 with electricity via a three phase-composed coupling reactor 3. Said motor is provided with two sets of windings of three-phase windings 11-23 with O1-O2 as neutral points, and respective windings are connected with two sets of three-phase arms 113-233 of said inverter via the windings 111-232 of three-phase cores 31-33 of the coupling reactor 3. In order to use the function of absorption and elimination of harmonic voltage by the coupling reactor 3 effectively, it is necessary that a given phase relation exists between a signal wave and a carrier wave. This means that a phase difference between signal waves of output voltage fundamental harmonics is set to pi/6 and phase differences between carrier waves with all phase are made equal to each other at the point of time when a sine wave signal increases from zero.
