Introduction:
EG8010 is a digital and fully functional pure sine wave inverter generator chip with dead zone control, which is used in DC-DC-AC two-stage power conversion architecture or DC-AC single-stage power frequency transformer boost conversion The architecture, with an external 12MHz crystal oscillator, can realize a pure sine wave 50Hz or 60Hz inverter chip with high precision, small distortion and harmonics. The chip adopts CMOS technology and integrates SPWM sine generator, dead time control circuit, amplitude factor multiplier, soft start circuit, protection circuit, RS232 serial communication interface and 12832 serial LCD drive module.
