He saved the library file as IR2110_UPDATED_FINAL_REAL.LIB and closed the laptop.
Infineon (which acquired International Rectifier) now provides free SPICE models. A community effort to convert these into a unified Proteus library would be invaluable.
Copy the existing USERDVC.IDX and USERDVC.LIB to a backup folder.
Repositories like Proteus-Libraries or Power-Electronics-Simulation often contain IR2110 parts. Look for files named IR2110.IDX and IR2110.LIB .
Proteus 8 came with many parts, but the IR2110 — with its tricky bootstrap capacitor, level shifting, and high-side floating supply — was missing. He needed to create it. Or find someone who had. ir2110 library for proteus 8 upd
: It includes under-voltage lockout (UVLO) for both channels to prevent MOSFET damage during low voltage. www.flywing-tech.com
The Bootstrap Paradox
: Backup the existing IR2110 library (if present) and then copy the new library files into the Proteus library folder.
To get the IR2110 High and Low Side Driver working in Proteus 8, you usually don't need a special external library "piece" because it is often included in the default library. If it is missing or you need a specific updated version, follow the steps below. 1. Check the Default Library He saved the library file as IR2110_UPDATED_FINAL_REAL
: Can withstand up to 500V offset voltage for the high-side floating channel. Current Capacity : Provides peak output current up to 2.5A. Bootstrap Operation
Select the downloaded file and follow the prompts to add it to your user library. 3. Manual Installation (For .LIB and .IDX files)
A correctly installed IR2110 library will show:
| Error | Probable Cause | Solution | |-------|---------------|----------| | "Unknown part IR2110" | Library not indexed | Restart Proteus; re-add library path | | "Model not found" | Missing .MODEL statement | Add MODEL=IR2110 in component properties | | Simulation fails at bootstrap | No initial low-side pulse | Add a startup circuit or initial condition for bootstrap cap | | Floating node error | VS node not referenced | Connect VS to load midpoint, not floating | | "Time step too small" | High dV/dt causing convergence issue | Reduce simulation speed; add snubbers or increase deadtime | Copy the existing USERDVC
By following this guide, you can successfully add the IR2110 library and simulate high-side/low-side driver circuits in Proteus 8.
Ensure the .LIB file was pasted into the correct path and the file extension is correct.
