When simulating complex switching circuits (like a 3-phase inverter), Proteus may display an error: "Simulation is not running in real time due to excessive CPU load".
Power electronics simulations can sometimes fail due to rapid voltage switching spikes. To fix this in Proteus: Go to in the top menu bar. Select Set Simulation Options .
For students: Stop building prototypes that explode. Simulate first. For professionals: Stop trusting abstract SPICE models that ignore the bootstrap. Use this library.
The IR2110 can drive a gate referenced up to 500V above ground. This library respects the VS (Floating Offset) pin. If you forget to connect the bootstrap ground reference, the simulation correctly fails. If you wire it correctly, the high-side output fires beautifully. ir2110 library for proteus 8
If you cannot find a compiled library file, you can manually import the manufacturer's simulation model. Infineon (which acquired International Rectifier) provides Spice models for the IR2110. You can follow the Infineon model import process to create a custom device. One user previously noted that by downloading the ".cir" file from Infineon and following Labcenter's tutorial to create a device, you can build a simulation block. (Note: This is an advanced workaround for when a precompiled library is not available).
Designing power electronics circuits requires reliable simulation tools to test component behavior before moving to physical prototyping. The IR2110 is one of the most popular high-voltage, high-speed power MOSFET and IGBT drivers used in inverter, motor control, and SMPS circuits. However, Proteus 8 does not always include a fully functional, simulation-ready IR2110 model in its default installation.
Adding a dedicated IR2110 library to Proteus 8 allows you to validate your switching logic, bootstrap circuit operation, and dead-time insertion before building a physical prototype. This comprehensive guide covers everything from sourcing the library files to running a successful simulation. Understanding the IR2110 and Why Simulation Matters When simulating complex switching circuits (like a 3-phase

). To fix this, open > Set Simulation Options in Proteus and change the solver settings to Relaxed or increase the ABSTOL and VNTOL tolerances.
Paste them directly into the Proteus folder located in Step 2. Select Set Simulation Options
Solution: Check if your Proteus installation utilizes the hidden C:\ProgramData folder structure instead of Program Files (x86) . Conclusion
Place a between VB (+ terminal) and VS (- terminal).
