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.

3.4 LED Warning Indication

EGS002 driver board provides LED warning indication function. User can determine problem

according 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 cycling

3.5 LCD Display Interface

EGS002 integrates LCD display interface for users’ convenience to test chip’s built-in display

function that EG8010 supports.Shielding cable is required for connecting EGS002 driver board and

LCD, otherwise inverter’s high voltage and high current environment will significantly interfere

driver board’s operation.

EG8010 supports 12832 LCD (default) orLCD3220 thatwe specifically designed. Because two

LCDs’ drivers are different, user has to specify if intends to buy LCD3220. Salesperson will ship

12832 LCD as default if not otherwise specified.

Note：

There are many modules of LCD in the market. EG8010 supports majority of 12832 LCD based

on control IC ST7920. Different LCDs may vary a little in pin map, name or description; user can

obtain information online.

5-3.TEST3 and TEST4 outputs unipolar modulation wave. When TEST3 and TEST4 are

connected to RC filter, it will output waveform shown as CH2 red waveform in figure 5-3.

4) Because pin VFB is grounded, undervoltage protection is going to turn on in 3 seconds.

Test1~Test 4 will all shut down; LED blinks four times, off for 2 seconds and keep cycling.

When EGS002 is connected to the power supply again, user can observe waveforms for another

3 seconds.
