About Power Electronics Hub

Power Electronics Hub is a collection of free calculators for designing and checking power conversion circuits: resonant and dual active bridge converters, inrush current limiting, gate-drive dead time, filters and control loops.

Every calculation runs in your browser. Nothing you type is sent to a server, and you do not need an account.

The site is built and maintained by a power electronics engineer who wanted quick, transparent design tools that show the equations behind each result. Each calculator page explains the method, lists the formulas it uses and gives a worked example.

The calculators use standard textbook and application-note methods, and their limitations are described on each page. Results are engineering estimates, not a substitute for datasheets, simulation and testing. If you find an error, please let us know.
