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.

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

according to the followings: z Normal：Lighting always on z Overcurrent：Blink twice, off for 2 seconds, and keep cycling z Overvoltage：Blink 3 times, off for 2 seconds, and keep cycling z Undervoltage：Blink 4 times, off for 2 seconds, and keep cycling z 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.

y 12832 LCD Connection Diagram：

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. y LCD3220 Connection Diagram：
