Master’s in Resonant and High-Frequency Converters — studying from the United Kingdom
Electronics and telecommunications form a significant part of the UK technology economy, with clusters in Cambridge, Bristol, Edinburgh, Belfast and the South East. Semiconductor design firms, defence electronics suppliers, telecom operators and Internet of Things companies all require embedded systems and communications engineers. Arm, headquartered in Cambridge, is a notable example of the design sector. Engineers work on hardware, firmware, signal processing and network infrastructure, often within regulated frameworks for radio and telecoms equipment.
Fees for the United Kingdom: £6,600 (Pound sterling), with instalments and employer sponsorship available.

Questions from the United Kingdom
Which UK bodies recognise electronics, embedded systems and telecom qualifications?
The Institution of Engineering and Technology (IET) is the main UK body for electronics, embedded systems and telecoms, and the British Computer Society (BCS) covers embedded software. Chartered and incorporated engineer titles are regulated through the Engineering Council. SEIUM's qualifications are private and not accredited by these bodies, so you should check with the IET how your study would be assessed.
Do UK electronics and telecoms employers hire people with private online qualifications?
UK electronics, semiconductor, telecoms and embedded systems employers usually assess candidates on practical design skill, hardware and software projects, and experience. A private qualification may help show specialist learning, but how much it counts depends on each employer. A portfolio of working embedded or telecoms projects is often decisive.
Is it realistic to study this online while working in the UK, and what level of English is needed?
Online study means you can keep your UK job and study from home, with no student visa required. Teaching is in English, so you need solid technical English. Your assigned technical tutor will help you plan your work. Fees are payable in instalments, and some employers offer training support, which varies by employer. Compare the programme hours with your schedule before enrolling.

How you'll learn
Training is 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 it fits around your job.
Each module combines theory, guided reading of the original standard and applied exercises. The working software is PLECS, LTspice, Ansys Maxwell, Frenetic and MATLAB Simulink, in free, academic or evaluation versions. Testing is studied through real procedures for double-pulse tests, bench efficiency measurements and EMC pre-compliance tests. Assessment is continuous by module, plus the final Master's Thesis.
Standards covered: IEC 62368-1, CISPR 32, IEC 61000-3-2, SAE J2954, Qi (Wireless Power Consortium), JEP180 (JEDEC), IEC 60747-9.
