How to Design an Overcurrent Protection Circuit Using LM358 Op-Amp Protection circuits are vital for any electronic design to be successful. In our previous protection circuit tutorials, we have designed many basic protection circuits that can be adapted into your circuit, namely, Over Voltage Protection, Short-Circuit Protection, Reverse polarity protection, etc. Adding to this list of circuits, in this article, we will learn how to design… |

Simple Constant Current Generator using Transistor Many of us who have worked with Analog circuits would have often come across the terms voltage source and current source in a circuit design. While anything that provides a constant voltage like a simple 5V USB output or a 12V adapter can be considered as a voltage source, the term current source always seems to remain a mystery. And many circuits, especially the one… |

Challenges that Make Setting up a Solar Farm Less Feasible Nearly 4.18 trillion kWh of electricity were generated in the United States at utility-scale electricity generation facilities in 2018, and around 17% was generated from renewable sources. The statistics recently published by the U.S. Energy Information Administration state that approximately 67 billion kWh of the total electricity generated in the country last year were… |

How to Design your own Transformer for SMPS Power Supply Circuits Designing an efficient Power Supply circuit is not less of a challenge. Those who have already worked with SMPS circuits would easily agree that the flyback transformer design plays a vital role in designing an efficient power supply circuit. Most times these transformers are not available off the shelf in the exact same parameter that suits our design. So in this… |

High Current Low Dropout Voltage Regulator Circuit using MIC29302 Whether it’s your Laptop, TV, Smartphone, or any other electronic device, they all operates at different voltages. These devices have sensitive components like Microprocessors, ICs, etc. that works on very low voltage, and even the slightest change in voltage can damage these components. These sensitive components require a steady and stable voltage to operate optimally. So… |

IoT based Lithium Battery Monitoring System for Solar Installation using ESP8266 The aim of this project is to monitor a Lithium Battery Bank remotely in a solar installation. It traces current individually for each Battery Pack. It also communicates with solar charger and calculates live values of power going to home and battery bank. It includes a web server with charts, internal historical data, and optionally can also upload data to Thingspeak and… |

How to design a 5V 2A SMPS Power Supply Circuit Power Supply Unit (PSU) is a vital part in any electronic product design. Most household electronic products like Mobile Chargers, Bluetooth Speakers, Power Banks, Smart Watches etc requires a Power Supply circuit that could convert the AC mains supply to 5V DC to operate them. In this project we will build a similar AC to DC power supply circuit with 10W power rating. That… |

+5V and -5V Dual Power Supply Circuit Most of the Analog Electronic circuits require dual power supply rails for proper balanced operation; this gets especially critical if we are designing Operational amplifier circuits. Negative supply voltage is also required in digital systems like A/D converters, op amps and comparators. In all these cases, the current requirement will be low, but generating such a -5V… |

All You Need to Know About Li-ion Batteries Unless some Tony Stark steps in and invents the Arc reactor or the research in Solar Power Satellites (SPS) for wireless Energy transfer gets through, we humans have to depend on Batteries for powering our portable or remote electronic devices. The most common type of rechargeable batteries that you find in consumer electronics is either Lithium ion or of Lithium Polymer… |

Howland Current Pump Circuit The simple current source is not perfect for variable loads as the current through load also changes with the load resistance. The solution for this problem is a Constant current source like Howland Current Pump Circuit. The Howland Current Pump was invented in 1962 by Professor Bradford Howland from MIT. It consists of an operational amplifier IC… |

What is Vacuum Tube and How does it Work You might be tempted to dismiss the good old tube as a relic of the past – after all, how can a few pieces of metal in a glorified light bulb hold up to the transistors and integrated circuits of today? Although tubes lost their place in the storefront of consumer electronics but they still remain insignificant use where there is need for a lot of power at very high (GHz… |

Understanding Low-Dropout Voltage Regulators (LDO) and its significance in Battery Operated Devices Today, electronic devices have shrunken in size than ever before. This enables us to pack in tones of features in compact portable devices like smart watches, fitness trackers, and other wearable devices, it also helps us to deploy remote IoT devices for cattle monitoring, asset tracking etc. One common thing among all these portable devices is that they are battery operated… |
