Abstract

PURPOSE:To obtain the balance of three phases without adjustment by a method wherein a quiescent period is produced over the all phases by means of one circuit, and the d.c. portion of each phase output voltage. CONSTITUTION:An inverter control ircuit 1 consists of an oscillator 11 and a pulse distribution circuit 12. The oscillator 11 generates a signal A according to which the pulse distribution circuit 12 generates signals in six phases, namely U, X, V, Y, W, Z. A quiescent period generation circuit 3 consists of a differentiation circuit 31 and a second gate circuit 32. Each conducting period of the signals U'', X'', Y'', W'', Z'' each having the quiescent period become equal, and the d.c. portion of each phase output voltage become zero, consequently making it possible to obtan simultaneously balanced three phases without adjustment.
