Abstract

This paper describes a prototype microprocessor controlled full-bridge pulse 2.5 kW (25 V, 100 A) current source that has been designed, assembled and tested. First a brief comparison between DC and pulse plating is presented with respect to the quality of coating. Then the arrangement of each switch, which consists of a parallel connection of eight MOSFETs (IRF-150) and their discrete time triggering method is discussed in detail. Experimental results, obtained from a prototype current source are presented to illustrate some programming possibilities achievable with the Motorola MC68HC11A8 microcontroller and show the good behavior of the scheme.
