This project is my experiment to produce a pure sine wave using the sinusoidal pulse width modulation (abbreviated SPWM) method, using Arduino Uno as an SPWM generator as a part of an Inverter. Because Arduino needs a circuit to drive High-Side and Low-Side MOSFETs to connect to Full-Bridge MOSFETs then […]

Protection and Buzzer Upgrade This post will explain adding a circuit to the H-Bridge circuit on the EG8010 datasheet. Done by adding a different protection function from the ES002 default and adding a Buzzer signal. What’s the difference? When a problem occurs such as under-voltage, over-voltage, over-current or over-temperature, the […]

Making a pure sine wave inverter is very easy using the EGS002, especially for low-frequency transformer-type inverters.All we need are some external components to make the H-Bridge driver and the step-up transformer. Test the newly purchased EGS002 module first before installing it on the H-Bridge circuit, see the post about […]

Faced an unexpected problem with a faulty PCB path, causing damage to the mosfet and possibly the EGS002 module as well. I immediately replaced the MOSFET fix the trace and also checked the EGS002 module on the tester as in my previous post, to make sure it was okay. Troubleshoot […]

When a problem occurs LED on the EGS002 module is blinking. The LED flashes several times according to the type of problem that occurs. The LED warning indication will flash twice when there is Over Current, three times for Over Voltage, four times for Under Voltage, and five times when […]

Functional Test EGS002: Updated December 22, 2021 The ordered EGS002 module has arrived and before installing it in the inverter it is better to do a functional test first, to make sure everything is functioning properly.!!! Preparation Before inserting the EGS002 into the header and conducting the functional test, first […]
