Once you download the library files (typically .LIB and .IDX or .HEX ), follow these steps to add them to Proteus: NirisonFabrice/SG3525-PWM-module - GitHub
What specific (e.g., inverter, push-pull converter, SMPS) are you trying to simulate?
Because Proteus does not officially distribute this component, the electronics engineering community has created reliable custom libraries.
It provides two alternating, totem-pole output drivers capable of sourcing and sinking high currents to turn MOSFETs or IGBTs on and off rapidly.
Once the library is installed, you should verify its functionality with a minimal test circuit. Place the SG3525 component and add:
Proteus is sensitive to floating pins. Ensure all unused shutdown or error pins are tied to either ground or VCC in a way that aligns with your schematic requirements. Conclusion
Tie Pin 16 (Vref 5V output) to Pin 2 (Non-inverting input) to set a reference voltage. Connect Pin 1 (Inverting input) to Pin 9 (Compensation output) to configure the error amplifier as a basic follower, or create a voltage divider to test PWM modulation control.

If the simulation fails or gives a "fatal simulator error," the most common cause is a missing or incompatible SPICE model. Your downloaded library might be a "schematic symbol only" (an empty shell) and lacks the necessary simulation model. Double-check your source to ensure you've downloaded a full model. Alternatively, if the component was imported, the path to the SPICE model in the SG3525.ASY file might be incorrect.
