Components needed for testing: - SG3525 IC - Resistors: 10kΩ (RT), 100Ω (gate drive) - Capacitors: 0.1µF (CT), 1µF (Soft-start) - MOSFETs: IRF540 (2 pcs) - Diodes: 1N4148, 1N5819 - Transformer (if testing push-pull)

Note: This is for advanced users only. The compiled .LIB method described above is sufficient for 99% of tasks.

The SG3525 is a popular PWM (Pulse Width Modulation) controller IC widely used in power electronics applications, such as switching power supplies, motor control, and lighting systems. Proteus, a powerful simulation software, is commonly used by engineers and students to design, simulate, and test electronic circuits. However, the SG3525 library is not included in the standard Proteus library, making it challenging for users to simulate circuits using this IC. In this article, we will guide you on how to download and install the SG3525 library for Proteus.
