DIY Breadboard Power Supply Circuit on PCB A Power supply unit is a very commonly used tool by most engineers during the development stage. I personally use it a lot when experimenting with my circuit designs on Breadboard or to power up a simple module. Most of the digital circuits or embedded circuits have a standard operating voltage of either 5V or 3.3V, so I decided to build a Power supply which can supply 5V/3.… |

Overvoltage Protection Circuit Protection circuits, like reverse polarity protection, short-circuit protection, and over/under voltage protection, are used to protect any electronic appliance or circuit from any sudden mishap. Generally fuse or MCB is used for overvoltage protection. Here in this circuit, we will build a simple overvoltage protection circuit without using a fuse. … |

Simple Bridge Rectifier Circuit The process of converting alternating current into direct current is rectification. Any offline power supply unit has the circuit for rectification which converts either the AC wall supply into a high voltage DC or stepped down AC wall supply into low voltage DC. The further process will be filtering, DC-DC conversion and etc. So, in this article we are going to discuss… |

How to make Solar Inverter Circuit We have limited natural resources and that too we are using in generating Electricity. That’s why there is lot of emphasis is given on generating and using clean energy. Today in this project, we will see how electricity can be generated from the sunlight, how it can be stored in the form of DC, and then how it is converted into AC to drive home appliances. … |

Short-Circuit Protection Circuit Short circuit protection is an unintended connection between two terminals which are supplying power to the load. It can happen both in an AC and a DC circuit. If it is an AC supply, then a short circuit can trip the power supply of the whole area, but there are fuses and overload protection circuits at many levels, from the power station to the house. And if it is a DC… |

Reverse Polarity Protection Circuit Batteries are most convenient power source to supply voltage to an electronic circuit. There are many other ways, to power up electronic devices, like adapter, solar cell etc but the most common DC power supply is Battery. Generally all the devices come with Reverse Polarity Protection Circuit but if you have any battery operated device which don’t have reverse polarity… |

Asynchronous Counter An asynchronous counter (or ripple counter) is a sequential digital circuit in which the outputs of flip-flops are connected in series, so that the output of one flip-flop serves as the clock input to the next stage. Not all flip-flops may change state at the same time as synchronous counters, so asynchronous counters are easier to design but may experience propagation delays. Table of… |
