  • Arduino SPWM generator

    Arduino SPWM generator

    ▶️ Watch on YouTube … Continuing work on my previous project, namely the generation of pulse width modulated sinusoidal waves called SPWM, I added an important function, namely voltage feedback in this Arduino SPWM generator project. In addition, I also added voltage, temperature, and battery protection functions. Protection is to protect against over-voltage, low voltage,…

  • Arduino Uno SPWM Inverter

    Arduino Uno SPWM Inverter

    ▶️ Watch on YouTube … 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…

  • Audible Alarm Protection

    Audible Alarm Protection

    ▶️ Watch on YouTube … 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…

  • EGS002: Simple Pure Sine Wave Inverter

    EGS002: Simple Pure Sine Wave Inverter

    ▶️ Watch on YouTube … 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…

  • EGS002: Troubleshoot & Repair

    EGS002: Troubleshoot & Repair

    ▶️ Watch on YouTube … 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…

  • EGS002: Audible Warning Indication

    EGS002: Audible Warning Indication

    ▶️ Watch on YouTube … 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…
