The SG3524 is a "Regulating Pulse Width Modulator" used heavily in DC-to-DC converters and inverter designs. Simulating it before building a physical prototype allows you to: Verify Frequency: Use the oscilloscope tool to see if your cap R sub cap T cap C sub cap T
A practical workaround used by many is to take a known working SG3524 design, like a PWM inverter circuit, and import it into Proteus as a base for your own projects. sg3524 proteus library download

The SG3524 is a monolithic integrated circuit designed for pulse width modulation (PWM) control. It is commonly used in switching power supplies, motor control, and other power electronics applications. The SG3524 features a voltage mode PWM control, adjustable frequency, and soft-start capability. Its high-performance characteristics, such as high efficiency, low power consumption, and high reliability, make it a popular choice among designers and engineers.
