Every Tool You Need. Nothing You Don’t.
A complete simulation environment purpose-built for power electronics.
Solver Technology
DSED Solver
DSIM computes only at switching transitions using its Discrete-State Event-Driven (DSED) approach — delivering results in seconds, not hours.
Physical Switch Models
Real semiconductor behavior for SiC MOSFETs, Si IGBTs, and diodes — including switching transients, conduction losses, and parasitic effects.
Robust Convergence
Strong convergence, even with hundreds of active switches. DSIM’s solver is designed for solver stability across complex topologies.
Thermal Simulation
Electro-Thermal Coupling
Simultaneous electrical and thermal simulation with bidirectional coupling. See junction temperatures evolve alongside electrical waveforms.
Accurate Loss Calculation
DSIM extracts electrical parameters of power switching devices from datasheets, then uses PAT models to precisely calculate switching losses with high fidelity.
Thermal Elements
Build Foster and Cauer thermal networks graphically. Model heatsinks, TIMs, cold plates, and ambient conditions.
Analysis & Visualization
Waveform Viewer
High-resolution oscilloscope-style waveform display with cursors, measurements, FFT, and multi-channel overlay.
Parametric Sweeps
Sweep any parameter (frequency, duty cycle, load, temperature) across thousands of combinations with automatic result collection.
Efficiency Maps
Generate full efficiency maps across operating conditions. Identify optimal design points automatically.
AC Sweep Analysis
With AC Sweep Frequency Analysis, the frequency response of a circuit or a control loop can be obtained, optimizing design and ensuring system stability.
Scripting & Integration
DSIM API (Python)
Full simulation control from Python. It integrates with mainstream AI frameworks, serving as an ideal simulation tool for AI algorithms, and empowers AI-driven power electronics design for research and engineering.
Custom C Blocks
Embed custom C code for control algorithms, digital controllers, and behavioral models. Compiled for maximum speed.
Co-Simulation
The Cosim Module provides interface for co-simulation between DSIM and MATLAB/Simulink, enabling users to fully utilize the complementary capabilities of both platforms.
DSIM API (MATLAB)
The API functions can be accessed through MATLAB, covering various simulation stages such as circuit modification, simulation control, and data post-processing.
DSIM API (C/C++)
Through the provided interface functions by DSIM API, users can leverage DSIM for parameter design, multi-scenario testing, and the integration of various custom features.
