A SG3525 PWM module simulation and PCB design using Proteus.
To confirm the library is working optimally, connect a virtual to output Pin 11 and Pin 14. Run the simulation to see if you get clean, alternating square waves with deadtime separation. Troubleshooting Common Errors "Component Not Found" in Search
The SG3525 features a high-performance PWM controller with a voltage-mode control loop, oscillator, and protection circuits. download sg3525 library for proteus better
