High-side floating supply and high-side floating return pins. This is where the bootstrap capacitor connects. HO & LO: High-side and low-side gate driver outputs. VCC & COM: Low-side fixed supply and power ground.
Even with a good library, simulations fail. Here is how to debug the most common problems.
If you cannot find a library that works, you can create your own simulation model. This is an advanced but powerful technique.
Search for trusted electronics simulation hubs or GitHub repositories. Common reliable sources include: Engineering projects blogs (like The Engineering Projects). GitHub repositories dedicated to Proteus models. Electronics simulation forums. Step 2: Download the Files
Place a VTERM or standard DC source for (5V) and Vcc (12V).
The high-side driver requires a floating supply. A functional library allows the user to simulate the external capacitor and diode that "boost" the voltage to drive the upper N-channel MOSFET.
Open the Component Mode in ISIS, click the 'P' button, and search for "IR2110." 3. Creating an IR2110 Simulation Schematic
To simulate the IR2110 when it is not in the default Proteus library, users must:
Open Proteus and create a new project or open an existing schematic. Click on the (P) button on the left toolbar. In the keywords search bar, type IR2110 .
To install the library, follow these steps:
Connect the HO pin through a 10-ohm resistor to the gate of your high-side MOSFET. Connect the LO pin through a 10-ohm resistor to the gate of your low-side MOSFET. Connect the high-side Source and low-side Drain together, and tie that node back to the VS pin. Troubleshooting Common Proteus Simulation Errors
Despite being a staple in real-world power electronics, the IR2110 hasn't always been a native component in older versions of Proteus. For years, users on forums like Electronics StackExchange and EDAboard have lamented that "IR2110 is not modelled natively" in Proteus ISIS.
