EGS002SinusoidInverterDriverBoardUserManual
1. Description
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.
