Basic power electronics in energy systems

The overall purpose of the course is to provide the student with a basic understanding of power supplies (uninsulated and insulated) in DC and AC converters as well as one-phase and three-phase circuits. In addition, courses include a basic knowledge of the use of switch mode power electronics in simple, regulated systems, eg in motor drives, renewable energy systems and amplifiers.

A student who has met the objectives of the course will be able to: describe and calculate the concepts of efficiency, mean value and power factor; classify converter types and pulse-width modulation; explain crucial properties of passive and active components in relation to power converters determine the time course of voltages and currents for the basic converter topologies (buck, boost and buck-boost) and derivatives thereof derive the transfer function for both the basic topologies and derivatives thereof; determine basic parameters, signals and power losses in power electronics circuits based on simulations; design transformers in galvanically separated topologies (f.x. forward, flyback, push-pull, half-bridge, full-bridge); determine basic parameters in switch mode circuits based on measurements on these; specify power converters and their components using English technical language under realistic working conditions for practicing engineers; clarify the operation of single-phase and three-phase pulse-width modulated inverters and pulse-width modulated rectifiers; explain crucial features of V / Hz control of three-phase AC machines and frequency converters; co-creation of all exercises and self-reflection on own learning and wellbeing in an engineering environment.
