The model might not include output stage supply separation. Check if Pin 13 (VC) is connected to the same supply as VCC.

Yes, if Proteus runs under Wine, copy the library files to the equivalent LIBRARY folder within the Wine filesystem. download sg3525 library for proteus

Remember: always verify your library with a basic simulation before committing to complex designs. If you encounter persistent errors, double-check the file locations or try an alternative source. With a working SG3525 model, you can confidently simulate everything from a 12V to 220V inverter to a high-frequency SMPS. The model might not include output stage supply separation

Introduction The SG3525 is a cornerstone of modern power electronics. As a pulse width modulation (PWM) controller IC, it is widely used in DC-DC converters , inverter circuits , SMPS (Switch Mode Power Supplies) , and battery chargers . For electrical engineers, students, and hobbyists, simulating an SG3525-based circuit before hardware implementation is crucial to avoid costly mistakes.
