Consultancy · Converter Development
Power converters engineered for efficiency, control & reliability
We design AC-DC, DC-AC, and DC-DC converters that perform in the real world — topology selection, magnetics, closed-loop control, simulation, prototyping, and efficiency & EMI testing. A simulation-first workflow built on the same power-electronics engineering we teach and ship, from 12 W to 2 kW.
PWM · InductorRegulated DC Output
Every converter is proven in simulation — switching, magnetics, and control — then verified on the bench for efficiency and EMI.

What We Deliver
Complete converter engineering, from topology to tested hardware
Power stage, magnetics, control, thermal, and EMI are engineered together — because a converter only works when every part of it works with the others.
Magnetics & Power Stage
Inductor and transformer design (core, turns, air gap, losses) with switch and diode selection, gate drive, and snubbers designed as one power stage.
Closed-Loop Control
Voltage- and current-mode control, compensator design, and stability (bode, phase margin) validated in simulation for clean, robust regulation.
Thermal & Reliability
Loss budgeting, heatsinking, and derating so the converter runs cool and lasts under real load, ambient, and stress conditions.
EMI/EMC-Aware Design
Layout, filtering, and switching strategy that keep conducted and radiated emissions in check and move you toward pre-compliance.
Testing & Efficiency
Measured efficiency curves, line/load regulation, ripple, and thermal data against targets — with iteration until the numbers hold.
Our Process
A clear, six-step path from spec to a tested converter
Predictable stages, checkpoints you can review, and a measured, working converter at the end.
Step 01 · Requirements
Requirements & Specs
Input and output voltage range, power level, isolation, efficiency, size, and environment are captured into a clear, testable specification.
- Input/output range & power defined
- Isolation, efficiency & size targets
- Environment & standards noted
Step 02 · Topology
Topology Selection
The right converter topology is chosen through a trade-off study and a feasibility check against your targets before any detailed design.
- Buck / boost / LLC / flyback evaluated
- Trade-off: efficiency, cost, size
- Topology confirmed vs. targets
Step 03 · Simulation
Simulation & Control Design
Power stage, magnetics, and closed-loop control are designed and validated in simulation — waveforms, efficiency, and stability — before hardware.
- Power stage & magnetics sizing
- Control loop & stability (bode)
- Waveforms verified before hardware
Step 04 · Prototype
Prototype & Magnetics
PCB layout, magnetics build, component sourcing, assembly, and the first power-up and bring-up of a real, working converter.
- PCB layout & magnetics build
- Sourcing & assembly
- First power-up & bring-up
Step 05 · Validation
Test, Efficiency & EMI
Bench testing for efficiency, regulation, ripple, thermal, and EMI — iterating until the converter meets every target.
- Efficiency, regulation & ripple
- Thermal & protection checks
- EMI pre-compliance & iteration
Step 06 · Delivery
Delivery & Documentation
Reports, schematics, magnetics details, BOM, PCB files, and measured data are handed over with a walkthrough so you can move forward with confidence.
- Reports, schematics & magnetics
- BOM, PCB files & test data

Why Power4All
A team that simulates, builds, and teaches converters every day
Power4All is a power-electronics education and engineering platform — so your converter is guided by people who live in both the theory and the hardware.
Simulation-first proof
We build our own converter simulators and virtual labs, so your design is validated and visualized before hardware — cutting cost and risk.
Real converter depth
AC-DC, DC-DC, and DC-AC across many topologies from 12W to 2kW — practical converter experience, not just slides.
Magnetics + control together
Power stage, magnetics, and closed-loop control are designed as one system, so regulation and efficiency actually hold up.
Efficiency & EMI focus
We design and measure for efficiency, thermal margin, and EMI so the converter is production-minded, not just functional.
Education-grade documentation
Because we teach, we explain. You get clear reports and documentation your team or examiner can actually follow.
Built to iterate
Converters rarely hit spec on the first build. We plan for measurement, refinement, and a second pass so the result truly meets target.
FAQ
Converter development — common questions
AC-DC front-ends and rectifiers (including PFC), the full range of DC-DC converters (buck, boost, buck-boost, SEPIC, Cuk, flyback, forward, LLC, and phase-shift), and DC-AC inverters — typically from 12W to 2000W for products, labs, and academic work.
We match the topology to your input and output range, power level, isolation needs, efficiency target, size, and cost. A short trade-off study plus simulation confirms the best choice before any hardware is built.
Yes. Inductor and transformer design — core, turns, air gap, and loss estimation — is part of the work, alongside the power stage, gate drive, sensing, protection, and closed-loop control.
Absolutely. We analyse and simulate your current design, then re-engineer the power stage, magnetics, layout, and control to improve efficiency, thermals, and conducted/radiated emissions toward pre-compliance.
