Abstract: The article is devoted to the implementation of a FPGA-based control system for an autonomous voltage inverter.
The urgency of the discussed issue. In recent years, in industrial mechanisms, there has been a transition from direct current motors to various types of asynchronous ones in applications requiring reliable maintenance of the torque or speed of the working body, which is justified by the reliability of machines of this type, and the absence of a collector device in them. At the same time, the range of various frequency converters and soft starters is expanding. There are attempts to transfer some of the functions responsible for generating inverter control pulses to CPLD FPGAs, however, most of such devices are based on microcontrollers with built-in pulse-width outputs.
The main aim of the study. Development of a technical structure, hardware and software architecture for a FPGA-based direct digital control system for an autonomous inverter.
The methods used in the study. Theory of electric drive, theory of automatic control, theory of automata, theory of algorithms.
The results. A functional diagram and structure of a FPGA-based direct digital control system of an autonomous voltage inverter are proposed. The modular structure of the system is proposed; the implementation of individual modules is shown. An algorithm for the functioning of a FPGA-based digital control system for an autonomous voltage inverter has been developed.
