ABSTRACT:
An improved priming and sweep-out circuit in which losses are obviated or minimized by transferring energy resulting from such processes back to the power supply, and wherein a single common storage inductance is used in a secondary winding circuit of a saturable-core inductor transformer, the primary of which is series-connected in the SCR-switching energy storage and discharge pulse generating circuit, to serve both in the priming and sweep-out functions, and wherein reset circuit inductance does not participate in the energy transfer or storage functions.
