This post is about the evaluation of the DC-DC Boost Converter in Synchronous and Non-Synchronous by utilizing the same hardware with different coding. In my previous post about DC-DC Boost Converter using Arduino Uno, it only discussed non-synchronous.. Table Of Contents I. Introduction A DC-DC converter is an electronic device […]

Introduction An Analog keypad is a type of keypad or button board connected to an analog input on an Arduino microcontroller. One of its advantages is its ability to detect many buttons using only one analog port so that it can save on port usage. For example, in the ATmega328p […]

In this project, I will build an Arduino Nano SPWM (sinusoidal pulse width modulation) generator using a TLP250 MOSFET driver. Introduction The TLP250 is a high-speed, low-power MOSFET driver with a single output and a wide voltage range. Then making it suitable for a variety of applications including SPWM generation. […]

I use this method from the ATmega328p application notes to make Zero Crossing Detector. Please check the following link for more details: https://www.microchip.com/en-us/application-notes/an2508 Simplest Zero Crossing DetectorCircuit The circuit uses two 1Mohm resistors to limit the current to less than 1mA at the microcontroller input port. Then connect directly to […]

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 […]

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 […]
