(Regulating Pulse Width Modulator) is not natively included in the standard Proteus component library. To use it in your designs, you must either download a third-party library or import a SPICE model for simulation. Finding and Downloading the Library
Monitor Duty Cycle Variation
: Watch the PWM duty cycle adjust in real-time from 0% to 100% as you vary the input load in Proteus.
