Introduction This article will serve as an introduction to the topic. It is aimed at the people who have been told by their management, “You are now my EMC person. Go figure out what it is and how we must deal with it!” It will not be an all-encompassing treatment of the subject, but it will provide the reader with a start and some ideas of where to go for more … [Read more...]
Securing New 5G Physical Assets with Electronic Access Control
The 5G era of mobile computing and communications is rapidly moving forward. 5G stands for the fifth generation of wireless infrastructure—a massive upscale of network technology. It will provide data transfer rates faster than the blink of an eye, reducing latency for even the most data-hungry applications, high bandwidth, and greater opportunities for connectivity and … [Read more...]
Würth Elektronik Introduces its WE-CST EE4.4 Current Sense Transformers
Würth Elektronik expands the product family of WE-CST current sense transformers with the new WE-CST EE4.4 series. An innovative manufacturing process not only makes these current sense transformers extremely small (4.7 x 4.65, 3.55 mm), but also provides better insulation. Their insulation voltage of 750 VAC, is 50 percent higher than that of market competitors. The WE-CST … [Read more...]
Demystifying EMC in an Electric Vehicle’s Drive Unit
1. Introduction The past decade has witnessed both a leap forward in technology and market expansion of the global electric vehicle (EV) industry [1]. With Tesla leading the market, followed by traditional vehicle original equipment manufacturers (OEMs) such as Volkswagen, PSA, and Toyota, to name just a few, the electrification of the automotive industry has been advancing at … [Read more...]
Review of Bonding and Grounding Requirements
The Question What is the required bonding and grounding requirements to achieve compliance with the various electromagnetic compatibility (EMC) standards associated with electronic equipment? I received this question a few days ago and quickly realized that a quick and easy answer was not feasible since I virtually had no knowledge of what kind of equipment types were … [Read more...]
EMC/EMI Challenges for the Connected Car
ABSTRACT Our automobiles are becoming more connected and reliant on wireless connectivity, and at the same time, the number of high-compute internal systems is rapidly increasing. Like any high-speed, complex digital electronic system, automotive electronics can be both a cause of, and highly sensitive to, electromagnetic interference (EMI), and the consequences of failure can … [Read more...]
EMC Simulation for Automotive Ethernet
Introduction The increasing use of electronics in vehicles introduces new risks of interference and crosstalk between components. OEMs and government regulators impose strict limits on electromagnetic interference (EMI) and electromagnetic compatibility (EMC), and redesigning a component that fails to meet these standards can be both expensive and time-consuming. This article … [Read more...]
PC Board Design for Wireless Products
INTRODUCTION TO SELF-GENERATED EMI It seems many manufacturers these days are developing products that incorporate wireless technologies—both in new and existing products. Many of these products are using LTE cellular connectivity and designers are finding that the on-board DC-DC converters and processor/memory bus noise are creating enough broadband electromagnetic … [Read more...]
How to Build Your Own EMI Troubleshooting and Pre-Compliance Kit
Electromagnetic compatibility (EMC) and the related electromagnetic interference (EMI) are some of the obstacles that must be overcome before nearly any electronics product can be brought to market—whether it’s an Industrial Internet of Things (IIoT) device, a consumer electronics product, or military and aerospace equipment. Products must not interfere with one another … [Read more...]
Würth Elektronik Circuit Board Technology Successfully Completes Research Project on Intelligent ARM-Hand Orthosis
In automobile production, industrial robots and production lines largely relieve people of having to work with heavy loads. This is not the case for people who work in a trade or in care, where the body can be heavily burdened by hard work. In the PowerGrasp project, a second skin provides additional strength. Following three years of research, the promising results are now … [Read more...]
