Hardware and Software of a Bipolar Current Source Controlled by PC

This paper describes a realization of a bipolar current source developed by the paper's authors. The source is intended for use in galvanic and other industrial plants, where a pulse-reverse current supply (with the desired shape in time) is required. A prototype of the device, which provides the outcome current intensity up to ± 50 A, has been constructed. The hardware of the source consists of a Pentium IV PC, a commercial ADDA converter, an interface of authors ￠ € original construction as well as a current regulator. The application software is developed using a commercial packet LabView as the basis.
