: Disconnect the feedback loops entirely and run the system in open-loop mode first. Verify the SPWM pulses using a 4-channel Proteus oscilloscope placed at the H-bridge outputs before trying to filter the wave or regulate the voltage.
: A digital chip that generates the Sinusoidal Pulse Width Modulation (SPWM) signals. It manages built-in safety parameters like over-voltage, under-voltage, over-current, and over-temperature tracking.
The standard application for the EGS002 is a topology. Below is the breakdown of the simulation setup.
The EGS002 is a widely used driver board for SPWM (Sinusoidal Pulse Width Modulation) pure sine wave inverters. It is based on the EG8010 digital generator chip and the IR2110S high-voltage, high-speed driver. Simulating this board in Proteus allows engineers and hobbyists to test inverter circuits without risking hardware damage. Understanding the EGS002 Architecture egs002+proteus+library+full
Inductor and Capacitor to smooth the output signal. Load: Resistive load. Simulation Steps:
Unipolar or bipolar SPWM (Sinusoidal Pulse Width Modulation).
Arrange four N-channel MOSFETs in a standard H-Bridge configuration. Connect the high-side output pins ( HO1 and HO2 ) and low-side output pins ( LO1 and LO2 ) from the EGS002 model directly to the corresponding gates of your H-bridge switches. Add small gate resistors ( ) to limit simulation ringing. : Disconnect the feedback loops entirely and run
The EGS002+Proteus+Library+Full boasts an impressive array of features, including:
It takes a DC input, generates pure sine wave PWM signals, and drives an H-Bridge to produce AC output.

Do not search for "EGS002 full library" – it likely doesn't exist legitimately. Instead, simulate using discrete blocks:
The EGS002 is a dedicated driver board designed for single-phase pure sine wave inverters. At its core is the EG8010 digital generator chip, paired with two IR2110S high-voltage, high-speed power MOSFET/IGBT drivers. Key Specifications and Features
Power electronics simulations in Proteus frequently encounter mathematical parsing errors due to rapid voltage changes ( dvdtd v over d t end-fraction ). Use these techniques to fix unstable simulations:
