A SG3525 PWM module simulation and PCB design using Proteus. download sg3525 library for proteus better
While Proteus is a powerhouse for embedded system simulation, many power electronics designers find that the default library often lacks a functional Pulse Width Modulation (PWM) controller. Finding a "better" version usually means sourcing a model that supports accurate timing and dead-time control for inverter or DC-DC converter projects.

If you cannot find a stable library, there is a workaround that advanced users love: importing a Texas Instruments SG3525 SPICE model into Proteus.
: Sites such as SnapEDA provide symbols, footprints, and sometimes 3D models for the SG3525AN. Note that these are primarily for PCB layout (ARES) rather than simulation (ISIS).
