describe
EG8011 is an enhanced pure sine wave inverter control chip. Applied to DC-DC-AC two-stage power conversion architecture or DC-AC single-stage power frequency conversion The voltage boost conversion architecture, connected to an external 20MHz crystal oscillator, can realize a pure sine wave 50Hz or 60Hz inverter with high precision, small distortion and harmonics. Special chip. The chip uses CMOS technology and internally integrates SPWM sine generator, dead time control circuit, amplitude factor multiplier, soft start circuit circuit, protection circuit, serial LCD driver module and other functions.
