Engineering workflow tool for magnetic component design with Pareto optimization, multi-loss analysis, and offline database support.
While reorganizing Buck inductor design workflows, one thing became increasingly obvious:
The real time-consuming part is usually not the first calculation.
It is:
- changing cores
- changing wire gauges
- thermal iteration
- copper/core loss trade-offs
- repeated parameter linkage
Traditional spreadsheet workflows work well at the beginning.
But once projects become more complex:
- multiple cores
- multiple materials
- multiple winding options
- thermal optimization
- loss optimization
the workflow becomes difficult to maintain.
For the same 24μH target:
Different core and winding combinations may lead to:
- 0.7W vs 2W+ total loss
- 50°C vs 130°C hotspot temperature
- completely different copper/core loss ratios
- different window utilization
- different skin-effect behavior
The difficult part is often not:
"Can it be calculated?"
but:
"Can dozens of engineering trade-offs be compared efficiently?"
- AP-method assisted core selection
- LI²-based toroid optimization
- Steinmetz / iGSE core-loss estimation
- AC copper-loss analysis
- Thermal co-estimation
- Pareto-front multi-solution comparison
- Core-winding joint iteration
- Offline engineering database
Instead of selecting cores and windings separately, the workflow jointly iterates:
- core selection
- winding selection
- thermal estimation
- copper loss
- core loss
- fill factor
- current density
Compare multiple candidate solutions simultaneously.
Useful for balancing:
- efficiency
- temperature
- size
- manufacturability
All calculations run locally.
Design data is not uploaded to external servers.
Useful for:
- factory environments
- confidential projects
- offline engineering workflows
Build your own reusable engineering database:
- core materials
- core models
- bobbins
- winding data
The database becomes part of accumulated engineering experience.
- Buck
- Boost
- Forward
- Interleaved Buck (multi-phase)
- CCM
- DCM
- BCM
Input:
- Vin range
- Vout
- Iout
- ripple target
- switching frequency
- thermal constraints
Joint iteration of:
- magnetic cores
- winding structures
- losses
- thermal estimation
with multi-solution comparison.
Generate:
- design summary
- loss analysis
- thermal results
- export files
Spreadsheets are flexible.
But once solution counts increase, maintaining engineering trade-offs becomes increasingly difficult.
The goal of this workflow is not simply:
"automatic calculation"
but rather:
reducing repetitive engineering iteration.
