THYRISTOR RECTIFIER LED BY PROGRAMMABLE LOGIC CONTROLLER WITH MODULAR DC/DC CONVERTER IN OUTPUT STAGE

In this paper was presented new model of rectifier based on programmable logic controller and touch panel. Significant difference in regard with previous series of rectifiers represents implementation of redundant parallel DC/DC converters toward the load, with constant voltage in all modes of battery charging. Another innovations were separate measurement and regulation of battery current and total rectifier current, as well as remote signalization of rectifier's currents and voltages by electrically isolated current loops 4-20 mA. Accomplished modifications of "soft start" function, battery presence check, regulators, protective functions and signalizations were also described.
