U.S. Patent 3,582,758 describes a circuit which uses transistors in a rectification function to take advantage of the low saturation drop. This article deals more generally with the use of a transistor, described in the IBM Technical Disclosure Bulletin 22, 2016-2017 (October, 1979), in such applications as both a rectifier and regulator operating either in a linear (dissipative) or switching mode. The described device typically can have an emitter-base breakdown of 40 volts and a Vce (sat) of 100 mV at a collector current of 50 A. The high emitter-base breakdown allows one to use this device as a combination rectifier-regulator, producing output voltages as high as 8 to 2O volts depending on supply technology.
