One platform, every stage of the design.
AirInduct Sim began as a wireless power coil simulator. It now covers magnetics, low-frequency fields, circuits and power electronics, PCB, thermal and compliance, with every result checked against reference cases.
Wireless power
Magnetics
Low-frequency fields
2D Field Solver
Free-to-try 2D finite-element solver in the browser for axisymmetric and planar magnetostatic and eddy-current problems: flux plots, inductance, force and losses, with frequency sweeps.
3D Low-frequency Fields
3D finite-element simulation of actuators, solenoids, eddy currents and magnetic shielding in the browser, checked against the TEAM Problem 7 benchmark.
Induction Heating & Eddy-current NDT
Simulate induction heating of billets, tubes and strips, eddy-current probe impedance versus lift-off, layers and conductivity, and magnetic shielding effectiveness, in the browser.
Circuits & power electronics
Circuits & Power Electronics
Browser circuit simulator for power electronics: DC, AC, transient, Bode and exact switching steady state in one solve. Opens LTspice .asc schematics. Runs on Mac, Linux, Windows and Chromebooks.
Loop & Stability Designer
Loop gain of a switching converter on the exact switching model: gain and phase margin, Floquet stability verdict, subharmonic map for peak current mode, and compensator auto-tune.
Bench-to-model
Upload impedance analyser or VNA data (Touchstone, CSV, LCR) and get identified parasitics with error bars and a passive SPICE model, by vector fitting.
Datasheet Device Models
Fit GaN and SiC FET models from datasheet curves, run a virtual double-pulse test, and get Eon/Eoff switching-loss tables with uncertainty bands.
Converter Designer
From input and output specs to candidate converter topologies, real parts and an efficiency, volume and cost Pareto front with error bands, each design verified by an exact steady-state simulation.
PCB & RF
PCB Coils & Antennas
Design planar spiral PCB inductors, NFC, RFID and Qi coil antennas with matching networks, and extract trace parasitics with a PEEC solver, in the browser.
PDN & Power Integrity
Power-integrity analysis in the browser: plane-pair cavity, decoupling capacitors and VRM, the PDN impedance Z(f) at the load against your target impedance, and a decap optimizer.
Thermal
Compliance
Conducted-EMI Predictor
Predict the conducted-emission spectrum of a switching converter through a LISN against CISPR 32, CISPR 25 or FCC Part 15.107 limits, with DM/CM split, peak, quasi-peak and average detectors, margin and a first filter.
High-frequency, EMC & Exposure
Wire-antenna and radiated-emission modelling against CISPR 32 limits, and RF field exposure against ICNIRP guidelines, in the browser.
How the modules fit together
A typical power-electronics design moves through several modules: choose a topology in the Converter Designer, size its inductor in the Magnetics Designer, simulate it in Circuits, check the control loop in the Loop & Stability Designer, predict conducted emissions in the EMI Predictor and the junction temperature in Electro-thermal. Each step reuses the data from the last.

Frequently asked questions
What can AirInduct Sim simulate?
Wireless power coils plus 14 further modules: magnetics design, 2D and 3D low-frequency fields, induction heating and eddy-current NDT, circuits and power electronics, PCB coils and NFC antennas, PDN and power integrity, conducted EMI, radiated emissions and RF exposure, control-loop stability, bench-to-model fitting, device models and junction temperature.
Do the modules share data?
Yes. A magnetic part designed in the Magnetics Designer can be used in the circuit simulator, measured parasitics from Bench-to-model feed the EMI and PDN models, and device models feed the electro-thermal and converter-design modules.
Do I need to install anything?
No. Every module runs in the browser. There is also a desktop app for macOS, Windows and Linux.
