Introduction
The EG8010 is digital, a function very well its own control of the dead time sinusoidal inverter chip generator, used in two stages DC-DC-AC structure energy conversion or single-stage DC-AC Industrial transformer Boost architecture, external 12 MHz crystal oscillator, to achieve high accuracy and the harmonic distortion is very small, 50 Hz or 60 Hz pure sine wave inverter ASIC. The chip uses CMOS technology, SPWM internal integration, a sinus generator, a dead time control circuit, a multiplier ratio range, a soft start circuit, a protection circuit, an RS232 serial interface, and a serial LCD display of the function driver module 1602.
