Universal Control System of a Semiconductor Electric Energy Converter on Programmable Logic Devises

The article presents the results of the development of a universal control system for semiconductor power converters based on a programmable logic devices (PLD). As a result of the work done, shared functional modules for the various control systems of semiconductor converters were determined, the features of implementing modules on programmable logic were considered, and the algorithms for controlling converters on mathematical models were studied. The principal circuit diagram of the universal control system of the converter is synthesized on the basis of a combination of programmable logic devises and a microcontroller. The topologies of printed circuit boards and their layout in a single module of the universal control system of the converter are developed; the built-in microcontroller software was written and debugged in the assembler language. An experimental sample of the control system was made and its joint tests with a prototype of a low-power three-phase inverter equipped with a load simulator were carried out, oscillograms of control pulses and output voltage were obtained in various modes of inverter control.
