WORKBENCH INDEX

Tools for every power electronics design decision.

Move from requirements and topology to circuit validation and physical component development in one workspace.

  1. 01

    System design

    Define requirements, compare topology options, and establish the direction of a DC-DC or WPT system.

    DC-DC Converter WPT System
  2. 02

    Circuit & simulation

    Draw schematics, inspect netlists, and validate circuit behavior with in-browser SPICE simulation.

    Circuit Editor In-browser SPICE Netlist / LTspice
  3. 03

    Components & 3D

    Develop capacitor banks, magnetics, transformers, and parametric coil models for the physical design.

AI ASSISTANT

Use WPT Design AI
to move faster

Use the design assistant AI to move faster, from initial reasoning to recommended component specs. You can also export the result in report form.

ELECHUB PLATFORM

One platform for design work and the steps that follow

APPLICATIONS

Connected design work, without pretending every tool is the same

System results can seed component design, selected parts can return to the source design, and magnetics can continue into 3D coil work.

SYSTEM DESIGN Wireless Power Systems

Pass compensation capacitor and inductor requirements into component design.

C, Vpk, Irms, f0 → Components
SYSTEM DESIGN DC-DC Conversion

Use calculated capacitor and inductor requirements to begin component design.

L, Ipk, ripple, fsw → Components
COMPONENT DESIGN Magnetics & Components

Develop capacitor and magnetic candidates, then apply a selected part back to the source design.

WPT requirements received DC-DC requirements received ← Selected part applied back Core, turns, wire, gap to 3D coil
CIRCUIT VALIDATION Circuit Editor & SPICE

Draw independently, inspect the netlist, and validate behavior with in-browser ngspice.
