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… |

DC Electronic Fuse Circuit Fuse is a vital protection device for many electronic devices. They simply monitor the current consumed by the circuit/load and in the event of unsafe current flowing through the circuit the fuse will blow itself and thus prevent the load/circuit form getting damaged by that high current. This type of fuse is called a mechanical fuse and there are many types of fuse such as… |

Electronic Circuit Breaker with High/Low Voltage Protection Voltage fluctuations have always been a problem and are responsible for most of the failure in AC appliances. Be it a normal home appliance like a Toaster or a high performance industrial machine like a CNC, everything has a rated voltage only on which it will run without any problem at its maximum efficiency. Unfortunately our Domestic/Industrial Lines fails to… |

High/Low Voltage Detection and Protection Circuit using PIC Microcontroller We often see voltage fluctuations in electricity supply at our home, which may cause malfunction in our home AC appliances. Today we are building a low cost High and Low Voltage Protection Circuit, which will cut off the power supply to the appliances in case of High or Low voltage. It will also show a alert message on 16x2 LCD. In this project, we have used PIC… |
