Řízení výstupního napětí nepřímého měniče frekvence s napěťovým meziobvodem

Abstract

Target of this diploma thesis is implementation of three chosen algorithms of output voltage control of frequency converter with voltage source inverter into a control system with DSP TMS320F28335, which allows operations with floating point. Principles of chosen methods of controlling the output voltage are explained in the thesis and above all the thesis deals with implementation of these methods into the application software of the processor and settings of its peripheries so they fulfill the desired function. A simple user interface is built in Labview for the need of communication between the control system and user. Implemented application software is finally verified by controlling the said frequency converter driving an asynchronous motor.
