AC Voltage measurement using PIC16F877A microcontroller

AC Voltage measurement using PIC16F877A microcontroller

Note: Microcontroller  PIC16F73  can be used instead of pic16f877a. This time we will see how to measure AC voltage parameters with the help of micro-controller. First we will know about AC voltage parameters, then we will do the whole work step by step. What is AC(Alternating Current): “In alternating current (AC, also ac), the flow of electric charge periodically reverses direction.

Switching Voltage Regulator Tutorial

Switching Voltage Regulator Tutorial

A switching voltage regulator is one of my favorite circuits. In school, they were the first circuits I built where I understood how transistors worked. In fact, they were the first circuit I saw an inductor being useful! Switching regulators are incredibly efficient when designed properly. Of course, this detail about design is important. They

How to use PWM to Generate Analog or Analogue Voltage in Digital Circuits

How-to use PWM to Generate Analog (or Analogue) Voltage in Digital Circuits

Many times, designers are faced with the need of generating analogue or analog voltage levels in purely digital circuits. Although the market provides today a very broad range of dedicated digital-to-analogue converters, putting such a device in the schematic has a negative impact on the overall cost of the system. 1. Introduction In the first
