For further assistance and resources, consider the following:
: Access the SG3525 PWM Module repository for a complete simulation and PCB design.
: Open your Proteus installation directory. The default path varies by version: download sg3525 library for proteus better
The is a legendary PWM controller chip. It is the gold standard for push-pull converters, DC-DC converters, and high-frequency inverters. However, despite its popularity, Proteus (the industry-standard simulation software) often ships without a native simulation model for the SG3525.
: SG3525 includes a critical feature to prevent "shoot-through" (both MOSFETs on a bridge turning on simultaneously) by adding a small delay between the outputs. In the simulation, you can introduce this delay by connecting a resistor to the Dead-Time (DT) pin to get realistic behavior. It is the gold standard for push-pull converters,
Power electronic simulations involve high-frequency switching, which can cause Proteus to stall or crash with a "Simulation is not running in real-time" error. To fix this: Go to > Set Simulation Options .
: C:\Program Files (x86)\Labcenter Electronics\Proteus 7 Professional\LIBRARY . In the simulation, you can introduce this delay
