Design efective power speed controller for 3-phase motor
 Uchytil, Filip ; Hanák, Pavel (referee) ; Lattenberg, Ivo (advisor)
This paper deals with the regulation of revolution of the asynchronous three phase engine with the frequency transformer. Firstly we will look into individual types of engines, the ways of regulation of the engines, the measuring of contemporary voltage and current at the engine and programming the ATMEGA64 microprocessor. The supervision is beeing handled by the PWM signal, which ensures low consumption of our circuit. The outputting part is comprised by the MOSFET transistors. The thesis devotes to communication of the ATMEGA64 processor via the USB port. The transmission ratio, voltage and even the contemporary current is displayed on the LCD monitor. The outcome of this thesis is the effective regulation of the asynchronous three phase engine, with the possibility of tracking all of the parameters mentioned above which are shown on the LCD display.
