What We
Do
01
Electronics Development
DC/DC & AC/DC Converter Design
Converter design is our core discipline. We deliver custom power converter solutions for demanding applications in automotive, telecom, and industrial power — engineered for high efficiency, thermal robustness, and long-term reliability.
Isolated & Non-Isolated Converter Design
We design a wide range of DC/DC and AC/DC converter topologies — Buck, Boost, Full Bridge, Flyback, Forward, LLC resonant, and phase-shifted full bridge — selected and optimised for your specific voltage, power, and efficiency requirements. Every design is supported by full analytical modelling and simulation before hardware is committed.
- Buck / Boost
- LLC Resonant
- Full Bridge
- Flyback / Forward
Control Loop Design & Stability Analysis
A converter that is thermally and electrically correct but control-loop unstable will fail in the field. We perform complete control loop design, time-domain and frequency-domain simulation, and hardware-in-loop measurements to validate stability across the full operating range — including load transients, input voltage variation, and temperature extremes.
- Small-signal modelling
- Compensator design
- Frequency-domain verification
- Stability validation
- Loop optimisation
Wide Bandgap Device Integration (SiC/GaN)
Silicon Carbide and Gallium Nitride devices unlock significant efficiency and power density gains — but they demand a fundamentally different approach to gate drive design, PCB layout, and EMC management. We have hands-on experience evaluating and integrating SiC/GaN devices in both automotive and DC fast-charging applications, helping clients extract the full performance benefit while managing switching noise and EMI.
- Device benchmarking
- Gate drive design
- EMI assessment
- Layout optimisation
Magnetic Component Design
Transformers and inductors are among the most project-specific components in any converter design. We design and specify custom magnetics — including wound-rotor and rotating transformer configurations — supported by FEM simulation where required, and validated against thermal and saturation limits.
- Custom transformers
- Inductor design
- FEM simulation
- Core selection
- Loss optimisation
02
EMI/EMC
EMI/EMC Design & Compliance
EMC failures are one of the most common and costly reasons for project delays. We embed EMC thinking from the earliest design stages — in schematic, layout, and system architecture — so that compliance is engineered in, not tested in at the end.
EMC-Driven Design
We apply EMC best practices throughout the design process: power stage partitioning, return current path management, filtering topology selection, and shielding strategy. Our experience spans automotive (CISPR 25) and commercial/industrial standards (EN 55022/32 Class A and B), and we design to the most demanding applicable standard from the outset.
- CISPR 25
- EN 55022/32
- Filter design
- Grounding strategy
- Risk assessment
PCB Layout for EMC & High-Power Applications
PCB layout in power electronics is an engineering discipline in itself. We perform layout for high-power, high-frequency designs with EMC compliance as a primary constraint — managing parasitic inductance in switching loops, isolating noisy and sensitive signal domains, and optimising thermal spreading. Our layouts are validated against both performance and manufacturing requirements.
- Loop minimisation
- Domain separation
- Thermal optimisation
- Impedance control
- Layout reviews
EMC Pre-Compliance Testing & Troubleshooting
When pre-compliance testing reveals issues, the clock is already running. We support clients through EMC pre-compliance test campaigns — setting up and executing measurements, interpreting results, and identifying root causes with precision. Where re-design is required, we define and implement targeted fixes rather than trial-and-error approaches.
- Near-field scanning
- Root-cause identification
- Targeted re-design
- Test reporting
- Chamber preparation

Electromobility
EV Power Systems
Electric vehicle power electronics represents some of the most technically demanding work in the industry — high voltages, extreme thermal environments, functional safety requirements, and relentless efficiency targets. Our consultancy brings direct, hands-on experience from leading EV development programmes.
Powertrain Inverter & Motor Drive Design
We support hardware development for powertrain inverters and electric motor drives — from requirements definition and system simulation through to schematic design, component qualification, and DFMEA. Our experience includes both the technical design work and the supplier management processes that industrialisation demands.
- Inverter hardware
- System simulation
- DFMEA development
- Component qualification
- Supplier evaluation
DC Fast Charging Systems
We have led the design and verification of power modules for DC fast charging infrastructure, including investigation of advanced resonant converter topologies for improved efficiency and reduced EMI. We support clients developing next-generation charging hardware — from power stage architecture through to prototype validation and standards compliance.
- Charging modules
- Resonant topologies
- Efficiency optimisation
- EMI reduction
- Prototype validation
On-Board Chargers & Vehicle DC/DC Converters
We design and consult on the full range of on-board power electronics — OBC systems, auxiliary DC/DC converters, and 48V architectures — applying automotive-grade design practices including functional safety considerations, component derating, thermal analysis, and supplier qualification support.
- OBC design
- Thermal analysis
- Component derating
- Supplier qualification
04
Embedded Systems
Embedded Control & Firmware
Power electronics hardware performs only as well as the control system driving it. We develop the embedded firmware and digital control implementations that make converters and drives behave as intended — across the full operating envelope.
Digital Control Implementation
We implement digital control algorithms for power converters and motor drives on microcontroller platforms — translating control loop designs from simulation into production firmware. Our work covers PWM generation, ADC sampling, closed-loop regulation, protection logic, and fault management.
- PWM generation
- Closed-loop regulation
- Protection logic
- Fault management
- MCU implementation
MATLAB/Simulink Modelling & Simulation
Before committing to hardware, we model and simulate converter and drive behaviour in MATLAB/Simulink — validating control strategies, stress-testing designs against worst-case operating conditions, and identifying design risks early where correction is cheap. Simulation deliverables can also serve as the basis for model-based code generation workflows.
- System modelling
- Control validation
- Worst-case simulation
- Code generation

Technical Consultation
Technical Consulting & Design Reviews
Not every engagement requires full design execution. We offer structured technical consulting for clients who need senior-level review, independent assessment, or targeted problem-solving on specific aspects of their development programme.
Design Reviews & Failure Analysis
We conduct structured design reviews of power electronics hardware — schematics, PCB layouts, and system architectures — identifying design risks, standards compliance gaps, and opportunities for performance improvement. For field failures, we perform root-cause analysis and define corrective actions based on our experience with similar failure modes across automotive and telecom applications.
- Schematic review
- Layout audit
- Failure analysis
- Risk identification
- Corrective actions
Technology Scouting & Pre-Studies
Evaluating a new converter topology, semiconductor technology, or system architecture? We provide independent, technically grounded pre-studies — assessing feasibility, quantifying trade-offs, and recommending the most viable direction before significant development investment is made.
- Feasibility assessment
- Trade-off analysis
- Technology benchmarking
- Architecture recommendation
- Risk quantification
Requirements Definition & System Architecture
Sound systems begin with well-defined requirements. We support clients in developing technical requirements documents, system block diagrams, and hardware/software interface definitions — establishing the technical baseline that design and supplier teams need to execute effectively.
- Requirements documentation
- System architecture
- Interface definition
- Supplier briefing
- Baseline establishment
Work with a specialist who has done it before.
Every project Elteknik takes on is handled personally by Odyssefs Lykartsis — a senior power electronics engineer with a decade of proven delivery across Ericsson, EVBox, and CEVT. If your project requires that level of experience, we would welcome the conversation.
