In this article I will explain how to upgrade an EGS002 inverter board to 5kVA power level using the HCPL-3120 or HCPL-J312 opto isolated drivers with isolated inputs and isolated power supply stages. However, the low side MOSFETs are driven through ordinary BJT totem pole configuration such as by using BD139 and BD140 transistor pairs. […]
EGS002
EGS002 Datasheet, Circuit Diagram Explained
The driver board EGS002 was created especially for single-phase sinusoid inverters. It makes use of an IR2110S driver chip and an ASIC EG8010 control chip. Protection against voltage, current, and temperature is included into the driver board. LEDs are used to indicate warnings, and fan control is included. Jumpers enable the setting of dead time, […]
Can EGS002 Work With a Standard 16 × 2 LCD?
Many people build inverter using EGS002, then they ask can we connect normal 16 × 2 LCD or not?? So the answer is yes, but not the way you may think. Understanding LCD Side Of EGS002 As we all know EGS002 is built around EG8010. That chip is dedicated SPWM sine wave inverter controller IC, […]
Making an EGS002 Equivalent Board using Arduino
The EGS002 board is nothing but a combination of a microcontroller with a H-bridge driver like the IR2110. So if you are interested to build your own EGS002 equivalent board with exactly identical features, then you can do it using the instructions given in the following article. So, here we are trying to build our […]
