With modern electroplating industrial development, three-phase high power factor rectifier circuit research in recent years has become a research hotspot, This paper is to design a keyboard can input parameters and the parameters of a three-phase power source electroplating current adjustment device. P89LPC938 SCM system to control as a core function with the corresponding circuit (such as screen, keyboard, protection), with software used in the C programming language structure SCM procedures, P89LPC938 use of the powerful function of coordinating the various parts together, realize the whole system needed to complete the function, system can be simplified through the keyboard input to regulate electroplating current adjustment of the output voltage, auxiliary functions to instructions, protection circuits, allowing the system to work stable and reliable.

Along with the modern galvanization industry development, thethree-phase power factor levelling circuit research became theresearch hot spot in recent years, this article is designs to beallowed and to have the three-phase power power source galvanizationcurrent regulator through the keyboard entry parameter which theparameter demonstrated. The system by the P89LPC938 monolithicintegrated circuit took the control core, unifies the correspondingfunction electric circuit (for example demonstration, keyboard,protection) composes, uses the C language programming structuremonolithic integrated circuit procedure in the software aspect, causeseach part of coordination using the P89LPC938 formidable function tounify in together, together realizes the function which the overallsystem needs to complete, the system may simple adjust thegalvanization current regulator through the keyboard entry the outputvoltage, assists to the function instructed, protects and so on theelectric circuit, stably causes the system work, to be reliable.
