Circuit technology and EMC

Overall Course Objectives

– To enable the student to select components for the realization of circuits according to applicable electrical, thermal, mechanical, environmental and production technological requirements.
– To introduce the student to the practical considerations to be taken into account when designing EMC-compliant Power Electronics and similar circuits.
