    Patent number: 4076974
    Abstract: A circuit for improved control of current for use in conjunction with an inductive load, for example, a transformer in a welding operation. The circuit of this invention is adapted to maintain the percentage of total RMS current demand directly proportional to a reference signal. A nonlinear control signal generator is provided to supply a control signal which is compared to the reference signal to operate a switch means for controlling the flow of current in the inductive load.
