...along with their contact details. If the course have external guest lecturers or such, give a brief description of their role and the company or similar they represent.
If needed, list administrative staff, along with their contact details.
Course purpose
Short description of the course purpose and content: can be copied from syllabus in Studieportalen. Additional information can be added.
Schedule
Course literature
List all mandatory literature, including descriptions of how to access the texts (e.g. Cremona, Chalmers Library, links).
Also list reference literature, further reading, and other non-mandatory texts.
Course design
Description of the course's learning activities; how they are implemented and how they are connected. This is the student's guide to navigating the course. Do not forget to give the student advice on how to learn as much as possible based on the pedagogy you have chosen. Often, you may need to emphasize concrete things like how often they should enter the learning space on the learning platform, how different issues are shared between supervisors, etc.
Provide a plan for
- lectures
- exervises
- laboratory work
- projects
- supervision
- feedback
- seminars
Should contain a description of how the digital tools (Canvas and others) should be used and how they are organized, as well as how communication between teachers and students takes place (Canvas, e-mail, other).
Do not forget to describe any resources that students need to use, such as lab equipment, studios, workshops, physical or digital materials.
You should be clear how missed deadlines and revisions are handled.

Learning objectives and syllabus
Learning objectives:
Describe turn-on and turn-off transients of a MOSFET using equivalent circuit models.
Design drive circuits for MOSFET and IGBT transistors, for driving and condition monitoring.
Describe how turn-on, turn-off and overvoltage snubber circuits are designed and how they operate.
Calculate component values for turn-on, turn-off and overvoltage snubbers based on circuit requirements.
Analyze the oscillations over a switching component in a real circuit and design a snubber circuit that reduces the oscillations. The improvements are also to be implemented on a real circuit.
Theoretically describe the function of a control circuit for a dc/dc-converter. Design and practically put a control circuit into operation and determine suitable component values in order to obtain voltage regulation, current mode control and over-current protection.
Calculate the current and voltage wave-forms in load-resonant (SLR), zero-voltage swtiching (ZVS) and zero-current switching(ZCS) resonant converters with the knowledge of initial current and voltage values.
Describe how HVDC converter systems and FACTS equipment (e.g. an SVC, TSCR or TCR) work and with which components such converters are realized.
Describe important aspects regarding power quality/EMI/EMC such as requirements, propagation, generation, effect and mitigation, as well as how to conduct measurements in such an environment.
Perform simplified calculations on how inductively and capacitively coupled disturbances propagate from source to victim.
Choose suitable filters for DC/DC-converters, EMI-mitigation and FACTS applications.
Describe how a diode, thyristor, GTO, BJT, IGBT, IGCT and a MOSFET are designed and how they operate.
Describe and conduct base calculations on different PFC circuit as well as isolated dc/dc converters such as the DAB and the current doubler.
Conduct thermal calculations on passive and active components.
Make base life-time calculations based on temperature profiles.
Describe inverters for drive systems and grid connected applications. Conduct loss calculations and describe the impact on the dc-link capacitor as well as surrounding components.
Describe the usage of energy storage systems (e.g. batteries and supercapacitors) in power electronic applications. Perform calculations on energy and power, as well as base thermal calculations on batteries and supercapacitors.
From an engineering point of view, be able to identity and select suitable components so that the demands are satisfied for the analyzed converter with respect to e.g. size and losses.
Model power electronic circuits using Spice based program and simulate and analyze impact on circuit performance and electrical stress on circuit components.

If the course is a joint course (Chalmers and Göteborgs Universitet) you should link to both syllabus (Chalmers and Göteborgs Universitet).
Examination form
Description of how the examination – written examinations and other – is executed and assessed.
Include:
- what components are included, the purpose of these, and how they contribute to the learning objectives
- how compulsory and/or voluntary components contribute to the final grade
- grading limits and any other requirements for all forms of examination in order to pass the course (compulsory components)
- examination form, e.g. if the examination is conducted as a digital examination
- time and place of examination, both written exams and other exams such as project presentations
- aids permitted during examinations, as well as which markings, indexes and notes in aids are permitted
Do not forget to be extra clear with project assignments; what is the problem, what should be done, what is the expected result, and how should this result be reported. Details such as templates for project reports, what happens at missed deadlines etc. are extra important to include.
