Title: Modulation system of flux control type inverter
Inventor: ISHII SHINICHI
IPC: H02M7/48
Filed: 1986-10-29
Abstract: PURPOSE:To restrain beat, included in the output current of an inverter, by a method wherein a time point, whereat a control signal outputted from a flux regulating means passes the zero point thereof, is controlled so as to coincide at all times with a time point, whereat a modulated wave passes the zero point thereof. CONSTITUTION:When a saturation detector 22 detects that a flux regulator 14 is saturated, an integrator 23 starts the operation thereof so that the output thereof is reduced gradually as a time elapses. A modulated wave from a modulated wave generator 15 is multiplied in a multiplier 24 by the output of the integrator 23, therefore, the modulated wave, inputted into a modulator 16, approaches to zero as the time elapses and becomes zero finally. The modulated wave is made zero in the manner as above, whereby the zero point passing time of the flux regulator 14 may become constant.
