Forward Converter Circuit There are various circuits or methods available for building Switched Mode Power Supply (SMPS). SMPS is used for generating controlled and isolated DC voltage from unregulated DC power source. Forward converter circuit is similar to the fly-back converter circuit but it is more efficient than fly-back converter circuit. Forward converter is mainly used for the application… |

Infineon's 1EDN7550 and 1EDN8550 Gate Drivers to Solve Ground-shift Issues in SMPS When a power MOSFET is switched on or off in a switched-mode power supply (SMPS), parasitic inductances cause ground shifts, which can lead to uncontrolled switching of gate driver ICs. Sometimes it may even result in electrical overloading of power MOSFETs and failure of SMPS. Infineon Technologies offers the 1-channel low-side gate driver ICs 1EDN7550 and 1EDN8550 in order… |

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.… |

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… |
