Reference link: https://pan.baidu.com/s/1-qtpNoOzpIF0zHOILA5DsQ Extraction code: v8yk EG8010 special chip for sine wave inverter 1. Product description EG8010 is a digital and fully functional sine wave inverter chip with its own dead time control. It is used in DC-DC-AC two-stage power conversion architecture or DC-AC single-stage power frequency transformer step-up conversion architecture. An external 12MHz crystal oscillator can realize a high-precision, distortion and harmonic pure sine wave 50Hz or 60Hz inverter dedicated chip. 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 and other functions. 2.
