Dr. Arjun Velez stared at the blinking red line on his oscilloscope simulation. It was 2:00 AM. His high-side MOSFET in the H-bridge was supposed to be switching beautifully at 50 kHz. Instead, it was oscillating like a drunken sailor, radiating heat in the virtual world of Proteus 8.
This time, the high-side gate voltage rose from 0V to 27V — 12V above the switching node. The virtual MOSFETs switched. The inductor current flowed. The simulation waveform looked beautiful . This is still a commonly cited path for many tutorials
| | Pin Name | Description | Connection | | :--- | :--- | :--- | :--- | | 1 | LO | Low-side gate driver output | To the gate of the low-side MOSFET | | 2 | COM | Low-side return path | Connect to VSS and ground plane | | 3 | VCC | Low-side power supply (10V-20V) | Connect to +12V | | 5 | VS | High-side floating return | To the source of the high-side MOSFET (the switching node) | | 6 | VB | High-side floating supply (+12V relative to VS) | Bootstrap capacitor (e.g., 10µF) to VS, and a fast diode from VCC | | 7 | HO | High-side gate driver output | To the gate of the high-side MOSFET | | 9 | VDD | Logic supply (3.3V-5V) | Connect to +5V (or tie to VCC via a resistor) | | 10 | HIN | High-side PWM input | Input from a microcontroller | | 11 | SD | Shutdown (active high) | Connect to GND if not used | | 12 | LIN | Low-side PWM input | Input from a microcontroller | | 13 | VSS | Logic ground | Connect to COM pin |
Ensure the (Logic Ground) and COM (Power Ground) are connected correctly. In most simple bridge simulations, these are tied together to a common ground point. Dealing with Simulation Errors If you encounter "Timestep too small" errors: Go to System -> Set Simulator Options . Select the "Power Electronics" template.

Ensure the COM pin is connected to the common ground of your low-voltage control circuit. Conclusion
He added a line in the model properties: + MODEL = IR2110.SPI
Paste these files into the LIBRARY folder located in Step 2. Step 4: Restart Proteus
If you can place the IR2110 but the simulation crashes with a "Simulation model not found" or "SPICE model missing" error:
