(17 -
EE425) Basic Information
Course specification
Course is active from 01.10.2005.. Basic course objective is to acquire knowledge about techniques of power electronic converter control, analysis of all elements in the controlled structure of the device, their modeling, calculation of the controller parameters, simulation of the device operation and finally entering and adjusting parameters in the real system and checking the obtained results. The goal is to unite these elements into a specific system of the power converter for the application in electromotor drives and elsewhere. Students are trained to know the methods of energy converter control, methods of control system analysis, methods and tools for converter modeling and to acquire the ability to measure properties on the specific devices and test their performance, and apply such device in the modern electromotor drives. Introduction. Basic components of management-control circuits. Sensors and adjusting circuits. Working principles and selection of control circuits. Structure and programme realization of digital control circuit. Management in electromotor drives – principles, methods, hardware. Management-control circuit for phase controlled converters. Principles, types and classification techniques of pulse-width modulation (PWM). Management-control circuits for power converters with PWM control (PWM chopper, PWM inverter). Modulation of space vector. Inverter control in the drive with electric machine and inverter connected to the electrical network. U/F, scalar, vector control. Alternating converter control. The course consists of the presentation of theoretical operation and design principles in the lectures, through practical work in the laboratory and independent work on designing the given project.
