Design Techniques for Reducing EMI in SMPS Circuits In my previous article on EMI, we examined how the intentional/unintentional nature of EMI sources and how they affect the performance of other Electrical/Electronic devices (victims) around them. The article was followed by another one on Electro Magnetic Compatibility (EMC) which provided insights into the dangers of EMI and offered some context to how poor EMI… |

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… |

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… |

12V 1A SMPS Power Supply Circuit Design on PCB Every Electronic device or product requires a reliable power supply unit (PSU) to operate it. Almost all devices in our home, like TV, Printer, Music Player etc. consists of a power supply unit built into it which converts the AC mains voltage to a suitable level of DC voltage for them to operate. The most commonly used of type of power supply circuit is the SMPS (Switching… |

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… |
