73924 - Power Electronic Circuits M

Course Unit Page

Academic Year 2018/2019

Learning outcomes

The goal of the course is to provide supplements of linear and non-linear electric circuits with special emphasis towards power electronic circuits. The main topics addressed in the course regards current and voltage harmonic distortion and powers in non-sinusoidal steady-state, Power diodes and SCRs, single phase and three phases rectifiers, Power electronic switches, emerging component, basics of pulse width modulation (PWM), single-phase and three-phase inverters and others. At the end of the course students master power electronics technologies with a special emphasis towards the automation field. The course provides basic in power electronics that are instrumental to the course “Electric Drives for Automation M”.
