EGS002 Sinusoid Inverter Driver Board User Manual
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.

Setting Description

JP1

When JP1 is short, it selects AC output frequency at 60Hz

JP5

When JP5 is short, it selects AC output frequency at 50Hz

JP2

When JP2 is short, it enables 3 seconds soft start mode

JP6

When JP6 is short, it disables soft start mode

JP3

When JP7 and JP8 are short, dead time is 300ns.

JP7

When JP3 and JP8 are short, dead time is 500ns.

JP4

When JP4 and JP7 are short, dead time is 1.0us.

JP8

When JP3 and JP4 are short, dead time is 1.5us.

JP9

When JP9 is short, LCD backlight is on
When JP9 is open, LCD backlight is off

The driver board’s jumperJP5, JP2, JP7 and JP8 are shorted as default setting, corresponding to
50Hz output, soft start mode on, 300nS dead time. Users can change these based on their needs.
Warning: Jumper of the same function CANNOT be short circuited at the same time. (For
example: JP1 And JP5 cannot be short at the same time.)

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

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

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
