EGS002 pure sine wave inverter SPWM driver board — EG8010 + IR2113S, 5V logic

The EGS002 is a ready-to-use pure sine wave inverter controller board based on the EG8010 ASIC and IR2113S MOSFET gate driver. It generates high-quality SPWM (Sinusoidal Pulse Width Modulation) signals to drive a full-bridge or half-bridge MOSFET stage, producing a clean pure sine wave AC output — all without any microcontroller programming. Simply connect your DC power stage, MOSFETs, and transformer, and the EGS002 handles the rest.

The board includes built-in protection and monitoring for output voltage, current, temperature, and fan speed. An optional LCD display (available as a variant) allows real-time monitoring of output voltage, current, frequency, and temperature directly on the board.

Key Specifications:

• Control chip: EG8010 (dedicated pure sine wave SPWM ASIC)
• Gate driver: IR2113S (high- and low-side MOSFET driver)
• Logic supply voltage: 5V DC
• SPWM output frequency: 50Hz or 60Hz (selectable via jumper)
• Dead time: adjustable via jumper
• Output waveform: pure sine wave (via external MOSFET bridge + transformer)
• Protection: over-voltage, over-current, over-temperature, short circuit
• Fan control: yes (temperature-based PWM fan speed control)
• LCD interface: yes (optional LCD for V/I/T/F monitoring)
• Jumper configuration: yes (frequency, dead time, soft start, etc.)

Key Features:

• No programming required — EG8010 ASIC generates SPWM autonomously; no MCU or firmware needed
• EG8010 + IR2113S combination — proven, reliable chipset for DIY and semi-professional inverter designs
• Full monitoring and protection — voltage, current, temperature, and fault protection built in
• LCD display support — optional LCD variant shows live output parameters
• Jumper-configurable — select 50/60Hz, adjust dead time, enable/disable soft start without soldering
• Fan speed control — automatic temperature-based fan PWM for thermal management

Variants:

• Without LCD — board only, no display module included
• With LCD — includes LCD display for real-time V/I/T/F monitoring

Applications:

• DIY pure sine wave inverter builds (12V/24V/48V DC to 220V/110V AC)
• UPS and backup power systems
• Solar inverter controller stage
• Power electronics lab and learning projects
• Off-grid and home energy systems

Note: The EGS002 is a driver/controller board only. External MOSFETs (e.g. IRF3205, IRFP260), a transformer, and a DC power source are required to complete the inverter. Refer to the EG8010 datasheet and EGS002 schematic for full wiring details.
