  • Boost Converter using Arduino Uno

    Boost Converter using Arduino Uno

    ▶️ Watch on YouTube … My post this time is about the DC-DC boost converter, which is a converter from 7V to 12V using Arduino. Here I try to design from start to finish. The first step for this design was determining the proper specifications for my purposes. What I need is the following: Vin…

  • Automatic Transfer Switch

    Automatic Transfer Switch

    ▶️ Watch on YouTube … This post is about an Arduino nano SPWM generator with added automatic transfer switch function. Used to switch the operation of the Inverter to the Grid when the battery voltage drops to a certain level. And it is done synchronously, i.e. the transfer is done when the grid and inverter…

  • Grid Synchronization

    Grid Synchronization

    ▶️ Watch on YouTube … This post is still continuing my project in Arduino Nano SPWM generator. I add some code and also Zero Crossing Detector circuitry for Grid Synchronization. The circuit is to detect the grid phase and the code is doing a task as Software Phase Loop Lock. Using Software Phase Locked Loop…

  • Arduino Nano SPWM at 24V/48V

    Arduino Nano SPWM at 24V/48V

    My Arduino Nano SPWM working voltage is 12V, we need to change the voltage divider network if we want to work with other voltages such as at 24V/48V. Voltage Divider Modification to 24V 48V My Arduino Nano SPWM Generator module detects 12V input from unregulated 12V coming from Battery, then display it on LCD. It…

  • Short Circuit Protection

    Short Circuit Protection

    ▶️ Watch on YouTube … Arduino Nano SPWM Generator Update This is an update to my previous post about the Arduino Nano SPWM generator by adding short circuit protection function. The method of Short Circuit detection is by checking the Voltage Feedback. When Short Circuit conditions occur the voltage detected will be very low, and…

  • Arduino Nano SPWM generator w/ LCD 16×2

    Arduino Nano SPWM generator w/ LCD 16×2

    ▶️ Watch on YouTube … Connecting the Arduino Nano SPWM generator to the LCD requires an additional connection on the PCB to the LCD. This additional connection is two wires for I2C communication and two more wires for the power source Added connection for Arduino Nano SPWM generator PCB I forgot to add an RC…
