Obtaining the download is the first step toward designing reliable inverter systems. By simulating the circuit, you can prevent damaging hardware components and refine the SPWM parameters to achieve a perfect sine wave output.

A means the simulation model accurately reflects the EG8010’s internal state machine. You need a model that reads the feedback voltage (Vfb pin) and adjusts the modulation index (MI) automatically. You need a model that reads the feedback
The EGS002 module is a dedicated, compact board. Proteus does not include it in its standard, default library set. A "full" library package generally includes:
Connect a power inductor (e.g., L1 = 1mH to 2.2mH ) in series from the output of the H-bridge.
