Pure sine wave inverter driver board EGS002 “EG8010+IR2110”

Description

The EGS002 is a high-performance, intelligent SPWM (Sinusoidal Pulse Width Modulation) driver board specifically designed for single-phase pure sine wave inverters. It combines the EG8010 pure sine wave ASIC (Application Specific Integrated Circuit) with the robust IR2110S high and low-side MOSFET driver ICs, providing a complete, ready-to-use solution for building professional-grade DC-AC power inverters .

Unlike modified square wave inverters that can cause humming in motors and are unsuitable for sensitive electronics, the EGS002 generates a true pure sine wave output with low harmonic distortion. This makes it safe to power laptops, computers, smartphones, medical devices, and inductive loads like fans and pumps .

The EG8010 chip integrates all the critical functions required for a modern inverter: a precise SPWM generator, dead-time control circuit, soft-start mechanism, and comprehensive protection features including over-voltage, under-voltage, over-current, and over-temperature protection . An external 12MHz crystal oscillator ensures high frequency accuracy and waveform stability.

The board features two IR2110S driver ICs configured to drive two separate MOSFET half-bridges, along with cross-conduction prevention logic for enhanced anti-interference capability . A voltage comparator (LM393) provides over-current protection feedback.

Housed on a compact 62mm × 33mm PCB, the EGS002 provides jumper-selectable configuration for output frequency (50/60Hz), dead time (300ns, 500ns, 1.0μs, 1.5μs), and soft-start enable/disable, eliminating the need for programming or external microcontrollers . An optional 128×32 serial LCD interface allows real-time monitoring of output voltage, frequency, temperature, and current .

Whether you are building a solar power system, a UPS backup, a wind power inverter, or a motor speed controller, the EGS002 driver board provides the intelligence and reliability required for both hobbyist and professional applications.
