Abstract
PURPOSE: To vary the amplitude of AC fondamental wave components through the control of lower harmonic wave by means of a comparatively simple controller.
CONSTITUTION: A device for controlling an inverter provides an output based on the difference in across the potential the output terminals between a frist unit inverter and a second unit inverter. Waveforms which undergo a grequent communtation suited to checking specified harmonic wave are previously memorized in a memory device. The timing at which the commutation waveform is rad out from the device 6 through a reference pulse generator 1, a divider 4, a subtractor/adder 5, a logical gate circuit 7, latch circuits 12 and 13 in accordance with numerae values indicated by a voltage indicator 2 is staggered by the inverters. Thus, the amplitude is varied in the foundamental wave component of the output voltage from the inverter.
