Carlos Ernesto Buonavita: Modular constant current power supply. Burroughs Corporation, Alfred W Kozak, Nathan Cass, Kevin R Peterson, June 28, 1977: US04032830 (19 worldwide citation)

A power supply employing a clock-driven D.C.-A.C.-D.C. converter having a current transformer in the A.C. section to develop a trapezoidal current feedback pulse train which is then converted to a trapezoidal voltage pulse train. A comparator compares the trapezoidal voltage pulse train to a voltage ...

Carlos Ernesto Buonavita: Power transistor switching circuit. Burroughs Corporation, Alfred W Kozak, Nathan Cass, Kevin R Peterson, May 17, 1977: US04024450

A circuit employing a transformer secondary winding having a fraction of its turns tapped across the base-emitter junction of a power transistor. A silicon controlled rectifier is connected from the transistor base across the entire secondary winding providing control of the power transistor conduct ...
