Design the converter.
Fix the problem.
Smart Power Test provides practical power-converter design review, Python automation, and root-cause analysis using public-safe examples and client-provided project inputs only.
Built as a personal engineering portfolio and service.
Smart Power Test is independent from any employer. The examples on this site are public-safe demonstrations and personal engineering work. No employer code, confidential project data, customer data, proprietary designs, or internal screenshots are used or shared.
Reports and reviews are for engineering direction, prototype preparation, and technical debugging. They are not final safety, EMI, thermal, automotive, production, or certification sign-off.
Three focused ways to work together.
The site is not limited to resonant converters. The core business is broader: converter design reports, Python automation for engineering workflows, and practical root-cause reviews for underperforming circuits or prototypes.
◢ Power converter design reports
- Buck, boost, buck-boost, flyback, forward, bridge, DAB, LLC, CLLC or CLLLC requirements
- Voltage, current, power, and switching-frequency targets
- Duty-cycle, gain, operating-range, or isolation requirements
- Proposed components, transformer ratio, or tank values if known
- Need for a clean engineering-style design report
- Best fit for early concept and prototype direction
◣ Python automation & root-cause reviews
- Python scripts for test, reporting, parsing, or engineering workflow
- Small desktop tools or automation helpers
- Root-cause analysis for circuits, prototypes, or design concepts
- Likely failure points and design red flags
- Practical next checks and recommended fixes
- Written review notes you can act on quickly
From problem definition to usable output.
Scope confirmed
You send the requirements, bug, or target output. I confirm what fits, what is missing, and what the final deliverable will be.
Analysis / implementation
Depending on scope, I model the converter concept, review the design evidence, analyze the likely failure path, or build the Python automation needed to solve the scoped engineering task.
Deliverable returned
You receive a design report, script/tool, or written root-cause review with practical next actions.
Featured demo: CLLC / CLLLC resonant-converter report engine
Built a public FHA-based design workspace that accepts resonant-converter requirements, explores tank behavior, searches candidate parameters, snaps to practical L–C values, plots gain curves, checks operating windows, and exports a design summary. This is a flagship demo, not the limit of the business.
Public-safe demo. No employer code, confidential schematics, or company project data are used. Other converter topologies can be reviewed or modeled depending on scope.
One live example:
resonant-converter report generation.
The demo page is one example of the engineering workflows Smart Power Test can build. It turns CLLC / CLLLC specs into tank-value candidates, gain curves, practical L–C constraints, operating-window checks, and exportable report text.
CLLC / CLLLC resonant-converter report engine
This is one full technical demo inside Smart Power Test: a resonant-converter workflow for topology inputs, gain sweeps, tank exploration, real L–C constraints, operating-window checks, and report-ready output. It opens on its own dedicated page so the main website stays focused on services, while this embedded preview keeps it visually connected.
This demo is not the whole business. Smart Power Test also covers buck, boost, buck-boost, flyback, DAB, Python automation, and root-cause reviews depending on scope.
Not only resonant converters.
Smart Power Test can support scoped design reports and reviews for common isolated and non-isolated DC-DC converter stages. The CLLC / CLLLC engine is the live demo, but the service is not limited to that topology.
Scope is confirmed before payment. Reports are for design direction, prototype preparation, and review — not safety, EMI, thermal, production, or certification sign-off.
Flyback review example.
A quick visual example of the kind of review and debugging work offered through Smart Power Test.
Find the weak point faster.
Send photos, traces, schematic fragments, or measured symptoms. The review focuses on likely failure points, suspect component choices, and the next checks worth doing.
Useful when a build looks wrong, runs hot, behaves strangely, or needs a second technical eye.
Choose the service that matches the problem.
Power Converter Design Reports
For converter concepts that need a cleaner design direction and an engineering-style report.
- Buck, boost, buck-boost, flyback, DAB, LLC, CLLC, CLLLC and related topologies
- Calculations, component sizing direction, operating limits, checks, and risks
- 48–72 hour turnaround for small scoped reports
Python Automation & Engineering Scripts
For engineers and small teams that need scripts, data handling, reports, or small workflow tools.
- CSV / Excel processing, report generation, parsers, calculators
- Small engineering tools and desktop helpers
- Quote-based when the automation scope is larger
Root-Cause Analysis & Design Review
For boards, converter stages, or prototypes that are unstable, underperforming, or clearly need technical review.
- Likely cause, red flags, and practical next checks
- Can be based on photos, schematics, traces, or measured symptoms
- Useful before you waste more time on a weak direction
Scope note: reports and reviews are for engineering direction, debugging, and prototype preparation. They are not final safety, EMI, thermal, production, or certification sign-off.
USD equivalents are approximate and shown for international clients. Final payment can be agreed in HUF, USD, EUR, Wise, Revolut, PayPal, or bank transfer depending on scope.
What this is not.
Smart Power Test is not positioned as a production-certification authority or a replacement for a full engineering team. It is for practical analysis, early design direction, automation, and review support.
Need a converter report, automation script, or technical review?
Send the project scope and I will confirm whether it fits the workflow and what can be delivered safely. Payment can be agreed in HUF or USD and handled by bank transfer, Wise, Revolut, or PayPal.
