micro corp.EGS002 DatasheetsEG8010 demo boardEGS002 Sinusoid Inverter Driver Board User Manual1. DescriptionEGS002 is a driver board specific for single phase sinusoid inverter. It uses ASIC EG8010 ascontrol chip and IR2110S as driver chip. The driver board integrates functions of voltage, current andtemperature protection, LED warning indication and fan control.Jumper configures 50/60Hz ACoutput, soft start mode and dead time. EGS002 is an improved version of EGS001 that is compatibleof EGS001’s original interfaces. EGS002 also integratescross-conduction prevention logic toenhance its ability of anti-interference, and LCD display interface for users’ convenience to usechip’s built-in display function.EG8010 is a digital pure sine wave inverter ASIC (Application Specific Integrated Circuit) withcomplete function of built-in dead time control. It applies to DC-DC-AC two stage power convertersystem or DC-AC single stage low power frequency transformer system for boosting. EG8010 canachieve 50/60Hz pure sine wave with high accuracy, low harmonic and distortion by external12MHz crystal oscillator. EG8010 is a CMOS IC that integrates SPWM sinusoid generator, deadtime control circuit, range divider,soft start circuit, circuit protection, RS232 serial communication,12832 serial LCD unit, and etc.2.

User can determine problemaccording to the followings: Normal:Lighting always on Overcurrent:Blink twice, off for 2 seconds, and keep cycling Overvoltage:Blink 3 times, off for 2 seconds, and keep cycling Undervoltage:Blink 4 times, off for 2 seconds, and keep cycling Overtemperature:Blink 5 times, off for 2 seconds, and keep cycling3.5LCD Display InterfaceEGS002 integrates LCD display interface for users’ convenience to test chip’s built-in displayfunction that EG8010 supports.Shielding cable is required for connecting EGS002 driver board andLCD, otherwise inverter’s high voltage and high current environment will significantly interferedriver board’s operation.EG8010 supports 12832 LCD (default) orLCD3220 thatwe specifically designed. Because twoLCDs’ drivers are different, user has to specify if intends to buy LCD3220.

Consider one final time the same 1 V, 1 Hz sinusoid, this time sampled every 0.75 seconds (4 3 Hz). Unlike the previous two cases, the resulting lowest frequency sinusoid that passes through this sequence of points is not a 1 Hz sinusoid, but rather a 1 3 Hz sine wave. It is clear Figure 3: (a) Sampling a 1 V, 1 Hz sinusoid at approximately .

There are around 78 million people who speak Korean around the world. [1] 한글 (the Korean alphabet) was invented by Sejong the Great in the 15th century. Before that time, people
