The EGS002 is a board unit designed for single-phase pure sine wave inverters. Using a single-phase pure sine wave inverter dedicated chip EG8010 as the control chip, the IR2110S driver chip. Driver voltage circuit board, current, temperature protection, LED alarm display and fan control functions, and can be set by jumper 50/60 hz output, soft-start function and dead zone size. EGS002 is an improved version of the EGS001 EGS001 interface that is compatible with the original. The EGS002 adds the locking function unit level to the original circuit, greatly increasing the board's anti-jamming capability. And increased the LCD display interface, easy to use display chip.
The EG8010 is a digital, fully functional, fully-sine wave inverter with dead-band control for DC-DC-AC two-stage power conversion architecture or DC-AC single-stage power supply transformer conversion impulse Architecture, 12 mhz crystal external oscillator, can achieve high accuracy, distortion and harmonics are very small 50 hz or 60 hz pure sine wave inverter ASIC. The chip uses CMOS technology, SPWM sine integrated internal generator, dead time control circuit, amplitude multiplier factor, soft-start circuit, protection circuit, RS232 serial communication interface and serial 12832 LCD driver module and other functions .
