Pure Sine Wave Inverter DC-AC SPWM Driver Board EGS002 met EG8010 IR2113 chips

Beschrijving

EGS002 is a driver board specific for single phase sinusoid inverter. It uses ASIC EG8010 as control chip and IR2110S as driver chip. The driver board integrates functions of voltage, current and temperature protection, LED warning indication and fan control.Jumper configures 50/60Hz AC output, soft start mode and dead time. EGS002 is an improved version of EGS001 that is compatible of EGS001’s original interfaces. EGS002 also integratescross-conduction prevention logic to enhance its ability of anti-interference, and LCD display interface for users’ convenience to use chip’s built-in display function. EG8010 is a digital pure sine wave inverter ASIC (Application Specific Integrated Circuit) with complete function of built-in dead time control. It applies to DC-DC-AC two stage power converter system or DC-AC single stage low power frequency transformer system for boosting. EG8010 can achieve 50/60Hz pure sine wave with high accuracy, low harmonic and distortion by external 12MHz crystal oscillator. EG8010 is a CMOS IC that integrates SPWM sinusoid generator, dead time control circuit, range divider，soft start circuit, circuit protection, RS232 serial communication, 12832 serial LCD unit, and etc.

G8010 is a digital, function very well bring their own dead-time control of pure sine wave inverter generator chip, used in two-stage DC-DC-AC power conversion structure or single-stage DC-AC power frequency transformer Boost architecture, an external 12MHz crystal oscillator, to achieve high precision, and harmonic distortion is very small, 50Hz or 60Hz pure sine wave inverter ASIC. The chip uses CMOS technology, the internal integration of SPWM sine generator, dead time control circuit, the multiplier factor range, soft start circuit, protection circuit, RS232 serial communication interface and a serial LCD driver module 1602 functions.
