Topology candidates
Candidate topologies for your voltage and power, compared on the same terms.
From specs to a verified converter.
Enter the input, output and power. Get topologies, parts and an efficiency, size and cost trade-off, each design checked in the circuit simulator.
What does the Converter Designer do?
The Converter Designer starts from your specification (input voltage range, output voltage and current, and constraints) and proposes candidate topologies, chooses switches, magnetics and capacitors from a parts catalogue, and estimates efficiency, volume and cost for each design with an error band. The results form a Pareto front so you can see the trade-off. Any design can be verified with an exact steady-state simulation in the Circuits module and exported as a netlist and bill of materials.
Features
Real parts
Switches, magnetics and capacitors chosen from a public parts catalogue.
Pareto with bands
Efficiency, volume and cost for every design, with error bands.
Verified and exportable
Exact steady-state verification, then netlist and BOM export.
Limits
Loss and cost figures are estimates with bands; verify the chosen design on the bench.
Every module ships with reference cases that run in our CI. See validation for how results are checked.

Frequently asked questions
Does it pick the components?
Yes. It selects switches, magnetics and capacitors from its parts catalogue and lists them in an exportable bill of materials.
How are the designs checked?
Each design can be verified with the exact periodic steady-state solver in the Circuits module.
