Abstract:

The saturable reactors were replaced by an electronic integrator, simulating operation of the saturable reactors with an improvement in accuracy of roughly two orders of magnitude. The entire control system was redesigned and reduced to practice following the discovery of insufficient accuracy in functional aspects, which were not apparent with operation of saturable reactors. A breadboard of the 260 watt unit except feedback and reference sources was established and brought to operation. An automatic adjustment of the system to the two line voltages in question, 115 and 230 v ac respectively, was devised. Electrical and mechanical design of units was completed and schematics established. Physical construction of experimental units is well advanced. Preliminary test data of the 260-watt experimtal model in dicate that all of the goals of this contract should be attainable. An active filtering ef fect of the FM-SS power modulator in excess of three was achieved, as expected, and secures the weight and size reduction of the bulky dc filters by a comparable factor. Weight and size re duction of the power transformer by application of inversion techniques exceeds expectations, and reduces this to a secondary problem.
