ABSTRACT:
A laser power supply includes a dc to dc converter which feeds a multiplier-rectifier circuit to provide a high dc voltage output. The converter includes a power transistor which is subject to a control of its on time to provide constant current regulation. A smooth regulation is provided by a proper timing of the turn off signal to the power transistor by sampling the emitter signal of a transistor which is included in a synthesized thyristor, the thyristor being operable to hog base current from the power transistor. The converter is coupled to the output multiplier-rectifier by a transformer which has a feedback winding connected in series with the base of the power transistor.
