Signals and systems in the time and frequency domain, principle of operation and design of basic analog and digital circuits, analog-digital conversion. Basic power electronic circuits, design of magnetic components and concept of force and torque generation, electromechanical energy conversion, principle of operation and characteristics of stationary and selected rotating electrical machines.

Introduction to AC circuits analysis, Fourier analysis, frequency and time domain, step response of electric circuits, Fourier and Laplace transform, frequency response of electric networks, two-port systems, differential amplifier, operational amplifier, basic and advanced operational amplifier circuits

Concepts from the lectures "Networks and Circuits I and II" explored through experiments, with inductive energy transmission systems (equivalent circuit parameters, transmission characteristics, resonance compensation, high-voltage generation) and photovoltaics (solar module characteristics, power flow adjustment with DC-DC converters, electro-mechanical energy conversion) used as examples.

Basics of the switching behaviour, gate drive and snubber circuits of power semiconductors are discussed. Soft-switching concepts, resonant operation of non-isolated as well as soft switching of isolated DC/DC converters are analysed in detail. Finally, the space vector modulation of three-phase inverters is introduced and the main power components are designed for typical industry applications.

The course presents control oriented modelling of modern power electronic systems for controlling power electronic circuits. Furthermore, modern concepts and the operation of high switching frequency 3-phase AC/DC converters (& AC/AC matrix inverters) are presented. Exercises using also simulation tools as e.g. PLECS are used to consolidate the concepts discussed.

Fields of application of power electronic converters; basic concept of switch-mode voltage and current conversion; derivation of circuit structures of non-isolated and isolated DC/DC converters, AC/DC and DC/AC converter structures; analysis procedure and analysis of the operating behaviour and operating range; design criteria and design of main power components.
