Abstract

The design, circuit, and performance characteristics of the current-regulation unit with a pass transistor bank in a linear mode is described. The unit was designed for building high-speed low-noise precision stabilized-current sources for a low-voltage load, for example, to supply the windings of magnetic systems of charged-particle accelerators. To build the current regulator using the described unit, an external DC power supply is needed. The required value of the output current can be achieved by the parallel connection of a proportionate number of units. For precision output-current regulation, overall current feedback can be applied.
