How you'll learn
Delivered 100% online on the SEIUM campus, with downloadable material, recorded classes and an assigned technical tutor. There are no fixed timetables: you progress at your own pace within each intake, so the programme fits around your job.
Each module combines theory, guided reading of the original standard and applied exercises. The working software is PLECS, SIMetrix/SIMPLIS, LTspice, MATLAB/Simulink and Infineon Designer, in free, academic or evaluation versions. Testing is studied through real procedures: ZVS verification with differential probes, efficiency measurement with programmable electronic loads and conducted emission tests on isolated converters. Assessment is continuous by module, plus the final integrating project.
Standards covered: IEC 62368-1, IEC 61204-3, CISPR 32, IEC 61000-3-2, EN 55011, IEC 62477-1, IEC 61851-1.
Build it end to end
Your final project follows the real engineering workflow, step by step, reviewed by your tutor.
