Would you like be involved in developing the electric drivetrains for the vehicles of the future? Then this is a course for you! The transition to an electric vehicle fleet entails an increased demand for competence in the field of electrical engineering. Engineers with expertise in power electronics and electric drive systems will play a central role in society's transition to electric vehicles.This course conveys a holistic perspective regarding electric drive systems, where students gain in-depth knowledge of how different components, and their properties, affect the electric drive system. This course is one of the entry requirements for further advanced courses in electrical control and support systems.

**Course content **

This course is designed to deepen the students’ understanding of power electronics, especially in their role in electrical drivelines. Students will learn the basic components in electric drivelines with special focus on the inverter and its controls. To support that knowledge, students will study:

• Semiconductor components – their basic operation and what differentiates their behaviors
• DC/DC converters – understanding them allows inverters to be more easily understood
• AC/DC rectifiers – a key component changing power system loading and necessary for large scale vehicle charging

DC/AC inverter – including their losses and harmonics and basic motor controls

**Examination **

KRA601 is a 5 HP course. It has two different forms of examination. The first is written assignments. In this class, that takes two forms: a check in assignment after each lecture consisting of problems similar to the example problems from class and simple questions to check understanding as well as three simulation lab completed in Simulink. The labs are designed to give students the ability to explore the concepts discussed in class quickly and safely. The other examination form involves reflection on the class content and on power electronics in society; there is a seminar where the students explain one concept from the class and how it is used in your daily work or as they are used in society.

Industry and academy

This course has been developed in collaboration with industry partners within the framework of one of our educational projects. The project aims to provide courses at advanced level to a mix of professionals and students to strengthen the Swedish industry's competitiveness.

We apply validation of work experience to see if you have knowledge that corresponds to the entry requirements for the course. Do not forget to attach your merits if you are applying based on work experience, the form is found here.

___________

Vill du vara med och utveckla framtidens elektriska drivlinor för elfordon? Då är detta kursen för dig! Omställningen till en eldriven fordonsflotta medför en ökad efterfrågan på kompetens inom området elektroteknik. Ingenjörer med expertis inom kraftelektronik och elektriska drivsystem kommer att spela en central roll i samhällets omställning till elektriska fordon.

Kursen förmedlar ett helhetsperspektiv kring elektriska drivsystem, där studenterna får fördjupade kunskaper om hur olika komponenter och deras egenskaper påverkar det elektriska drivsystemet. Denna kurs ger behörighet till ytterligare fördjupningskurser inom elektriska styr- och stödsystem.

Industri och akademi

Denna kurs är framtagen i samverkan med industrin inom ramen för ett av våra utbildningsprojektet. Projektet syftar till att ge kurser på avancerad nivå till en mix av studenter och yrkesverksamma för att förstärka den svenska industrins konkurrenskraft.

Vi tillämpar validering av arbetslivserfarenhet för att se om du har kunskaper som motsvarar behörighetskraven på kursen. Glöm inte att bifoga meritförteckning om du söker baserat på arbetslivserfarenhet, blankett finns här.
