GeckoCIRCUITS – circuit simulator optimized for power electronics

GeckoCIRCUITS is a circuit simulation environment designed specifically for power electronics applications. It provides a fast and user-friendly platform for modelling, analysing, and visualising electronic systems, combining circuit simulation with control and thermal modelling capabilities.

Originally developed by researchers associated with ETH Zurich, the software supports a wide range of simulation tasks including time-domain analysis, system modelling, and optimisation workflows. Its modular architecture and programmable components make it suitable for both educational use and advanced engineering design.

This is free and open source software.
