Product Detail
EG8010 pure sine wave inverter dedicated chip
1, product description
EG8010 is a digital, fully functional pure sine wave inverter
generator chip with dead zone control. It is applied to DC-DC-AC
two-stage power conversion architecture or DC-AC single-stage power
frequency transformer boost converter. Architecture, external 12MHz
crystal oscillator, can realize pure sine wave 50Hz or 60Hz
inverter chip with high precision, 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 driver module.
