Advanced Solution for Power Electronics Simulation
The ultra-fast simulation platform for power electronics, delivering speeds hundreds to thousands of times faster than traditional tools. Powered by its unique Discrete-State Event-Driven (DSED) technology, DSIM effortlessly handles complex switching and multi-scale systems—enabling analyses that were once impractical, and dramatically accelerating development while cutting costs.
DSIMDSIM’s DSED approach computes only at switching transitions, allowing DSIM to run much faster while maintaining high accuracy.
Performance
without Compromise.
DSIM’s DSED approach is designed to deliver major speed improvements over commercially available solvers — without sacrificing the accuracy required for high-frequency switching analysis.

Beyond System Simulation —
Down to Every Switching Transient
DSIM uses innovative Piecewise Analytical Transient (PAT) models that decouple the key switching characteristics of semiconductor devices from first principles.
Nanosecond Resolution, System-Level Simulation
PAT models efficiently solve turn-on and turn-off processes for IGBTs, SiC MOSFETs, and more — extending time resolution down to nanoseconds even in large system simulations.
Multi-Timescale Unified Modeling
Device-level PAT models build into system-level models with conditional timescale decoupling, significantly reducing numerical stiffness and ensuring fast, convergent simulation.
100+ Built-in Device Models
Covering hundreds of mainstream IGBT and SiC MOSFET devices, ready to use out of the box.
Direct Thermal-Electric Coupling
Switching transient results directly feed loss calculations and thermal dissipation simulation — evaluate junction temperatures and system thermal topology in real time.
