Step 3 —The behavioral model. Proteus lacked an official IR2110 SPICE model, so Raj built a behavioral macro: comparators for UVLO, controlled sources to emulate the high-side floating reference, timed switches for the bootstrap recharge window, and the gate drivers’ output stage with realistic Rg and saturation characteristics. He tuned the LO and HO output drive strengths and dead-time behavior to match datasheet rise/fall times across typical gate capacitances.
Typically, the library folder is located at: C:\ProgramData\Labcenter Electronics\Proteus 8 Professional\Data\LIBRARY (Note: ProgramData is a hidden folder by default in Windows).
Simulating power circuits without the right gate driver models leads to inaccurate results. This post walks through how to download and install the updated IR2110 library for Proteus 8. 1. Download the Library Files ir2110 library for proteus 8 upd
: Connect a fast-recovery diode from VCC to VB, and a bootstrap capacitor between VB and VS. This is vital for the high-side gate driver to function.
The IR2110 is a high-voltage, high-speed power MOSFET and IGBT driver with independent high- and low-side referenced output channels. Step 3 —The behavioral model

When building power electronics projects like motor drivers, pure sine wave inverters, or switching-mode power supplies (SMPS), the IR2110 IC is crucial. Without the specific library files, Proteus will display a "Model Not Found" error during simulation, or you will only be able to place the schematic component without testing its electrical behavior. An updated Proteus 8 library provides: open Windows File Explorer
This article provides a complete guide on how to download, install, and use the updated , ensuring you can simulate your circuits accurately. 1. What is the IR2110?
Tip: If you cannot see the ProgramData folder, open Windows File Explorer, click on the tab at the top, and check the box for Hidden items .
: Connect the IR2110 with other circuit components according to the design requirements. This may include MOSFETs, diodes, resistors, and a power source.
The updated IR2110 library for Proteus 8 should ideally include:
