Induction Motor Working Principle- Single Phase and Three Phase Induction Motor The induction motor is an A.C electrical machine that converts electrical energy into mechanical energy. Induction motor is used extensively in variously applications from basic domestic appliances to heavy industries. The machine has so many applications that are hard to count and you can imagine the scale by knowing that almost 30% of electrical power generated globally… |

Interfacing ADXL345 Accelerometer with Arduino UNO We all know about accelerometers and gyroscopes; they are primarily used to detect acceleration. While an Accelerometer can measure linear acceleration, the gyroscope can help find the rotational acceleration. A gyroscope is used to measure angular velocity, which uses the Earth’s gravity to determine the orientation of the object in motion. There is a sensor like… |

What is Power Transformer and How does it work? In some of our previous articles we have discussed about the basics of the transformer and its different types. One of the important and commonly used Transformer is Power transformer. It is very widely used for stepping up and stepping down the voltage at the electrical power generating station and distribution station (or substation) respectively. … |

What is PoE and How Power over Ethernet Works Internet connectivity has become necessary nowadays as almost every electronic device needs an active internet connection to work properly. Although most of the devices have Wi-Fi connectivity options, but many devices and network routers still used Ethernet ports and cables to connect with the wired internet line. We previously learned about how data can be transferred over… |

Three Phase Inverter Circuit - 120 Degree and 180 Degree Conduction Mode We all know about an inverter - it is a device which converts DC into AC. And we previously learned about Different types of inverters and built a single-phase 12V to 220V inverter. A 3 Phase Inverter converts the DC voltage into a 3 Phase AC supply. Here in this tutorial, we will learn about the Three-Phase Inverter and its working, but before going any further, let… |

Frequency Compensation of Op-amp and why it is important in your Op-Amp Circuits Operational Amplifiers or Op-Amps are considered the workhorse of Analog Electronic Designs. Back from the Analog computers era, Op-Amps have been used for mathematical operations with analog voltages, hence the name operational amplifier. To date, Op-Amps are extensively used for voltage comparison, differentiation, integration, summation and many other things. Needless to… |

An Introduction to Solenoids Solenoids are simple components that can be used for various applications. The name solenoid is derived from the Greek word “Solen” which means a channel or a pipe. Solenoids are used in both domestic and industrial equipments, they are available in various designs, each of them has their own specific applications. Although the application changes, their working principle… |

Diode Clamper Circuits Previously we learned about Clipper Circuits, which are used to clip off the positive or negative part of the Alternating waveform. Today we will learn about Clamper circuits which are used to clamp the DC level of the output signal without distorting the waveform i.e. they are Level Shifter circuits. It can be designed using capacitor, diode and resistor. The… |

Diode Clipper Circuits: Design & Demonstration As the name suggests, Clipper circuit is used to “clip” a portion of input signal without distorting the remaining part of the waveform. It is a wave shaping circuit. This can be very useful in the circuits where the input signal attains a higher value of voltage than the expected one. These circuits can be implemented in various ways according to the configuration or… |

Mains Power Supply Failure Alarm Circuit Although there are inverters and generators to immediately start the AC power supply whenever there is a power cut but sometime when there is no backup support and we have some critical machines running to perform some important task, it’s a good idea to atleast have an alarm which notify us as soon as power goes off. In this tutorial, we will learn how to make a simple… |

RC Phase Shift Oscillator using Op-Amp When an RC phase shift oscillator employs an op-amp in its circuit, it becomes an electronic oscillator with a stable sine wave output. It functions by developing two groups of 180-degree phase shifts, one via the RC network and the other via an op-amp in an inverting circuit. Due to this phase shift arrangement, it produces nearly pure sinusoidal signals with extreme frequency stability and… |

IoT Smart Meter - Monitor your Electricity through the Wi-Fi Link Imagine how nice it would be if you can see the energy consumption of your house or any commercial apartment sitting anywhere in the world. Doesn’t it sound cool? That introduces the concept of Smart Metering. So what is smart meter? – A smart meter is an electronic device which is trending from 15 years which records the consumption of electricity and gives information to… |
