ABSTRACT:
An apparatus for controlling a current type inverter including a bridge circuit of bridge-connected self-extinguish elements triggered by pulse width modulation signals. A current is provided for applying a single or plural triggering pulses having a desired pulse width to those self-extinguish elements connected in series with the other self-extinguish elements forming the pairs in the bridge circuit and which other self-extinguish elements are turned on by the pulse width modulation signals. By the above manner of control, the current type inverter can generate output currents of sinusoidal waveform, and the value of the output currents can be controlled over a very wide range.
