The most reliable sources for these models are the semiconductor manufacturers themselves. Most provide SPICE models for free on their product pages:
: Provides high-accuracy G2 models specifically optimized for transient characteristics in power devices.
: Offers one of the largest libraries for discrete products, including IGBTs and SiC devices.
: If you are working with Silicon Carbide (SiC) modules, you can download comprehensive zip files containing both .lib and .asy files.
: A community-driven resource where you can find user-contributed models for older or niche parts. 2. How to Import the Model into LTspice
Once you have downloaded the .lib (library) or .sub (subcircuit) file, follow these steps to use it:
: Offers a streamlined download page for both LTspice and PSpice IGBT models.
Finding and downloading the right is essential for accurately simulating high-power switching circuits like inverters and motor drives . While LTspice comes with a basic library, most high-performance IGBTs from major manufacturers require external model files. 1. Where to Download IGBT LTspice Models
