2.  " Power Electronics 2. Laboratory course " DTU course no. 34653,  5 ECTS,   Duration of Course:  January 3 weeks

Course Contents:

This course is a natural continuation of 34652 Power Electronics 1. The course goal is to provide the students with knowledge about the practical considerations when designing switch mode converters. 

Further to enable the student to build a switch-mode converter (incl. error finding and noise attenuation) and to teach the students practical considerations concerning measurements on switch-mode converters, including verification of the specs. 

Produce and measure magnetic components. EMC aspects. Filter design. Practical considerations w.r.t. construction of - and measurement on switch-mode converters. Analysis and measurement of small-signal Transfer function - Loop stability. Slope-compensation. Input- and output impedance.
