ABSTRACT:
Electric power converter with load compensation, especially for electrical loads subject to fluctuations in demand for power, such as arc furnaces, welders, etc. An external source of electrical power is applied to a stationary input winding of the converter to produce a movable polyphase magnetic field coupled to an output winding movable at least in part over a limited range relative to the input winding. The movement is resisted by an interposed resilient member adapted to position the output winding to match the output to the input power demand of the load equipment thereby counteracting whatever fluctuations tend to occur in load resistance and current.
