FDA Issues Guidance on EMC of Electrically-Powered Medical Devices
The U.S. Food and Drug Administration (FDA) has released a draft guidance document containing a list of recommendations for medical device companies who want to claim electromagnetic compatibility (EMC) of electrically-powered products for premarket submissions. Typically, the review of EMC information in a submission is based on the risk associated with EMC malfunction or degradation of... Read More
Inductive Wireless Charging Products Must Comply with These Emissions & SAR Requirements
Manufacturers of new technologies often struggle to determine what electrical compliance regulations apply to their products. Here is a basic guide for inductive wireless power products, like the wireless mobile phone chargers that are gaining more market penetration. This post is derived from an Intel Corporation presentation given at the recent FCC TCB Council Workshop... Read More
Pre-Compliance EMC Testing Saves Cost and Accelerates Speed to Market
You have designed and built a great new electrical product that meets market demands and trumps competitive offerings. You are confident that it doesn’t radiate much energy and is not susceptible to outside interference. Yet when you do final EMC testing, your product fails. This is the nightmare scenario for product designers. Unit redesign and... Read More
EU Inverters Mostly Non-Compliant to EMC Emissions Requirements in EN 55011 and EN 61000-6-3
In the first half of 2014, the European Union’s EMC Administrative Cooperation Working Group (EMC ADCO) performed a cross-border EMC market surveillance campaign to assess the compliance of grid-connected solar panel inverters (and optimisers) intended to be used by consumers. Inverters allow electricity generated by solar photovoltaic (PV) modules to be fed into the mains... Read More
EMC Testing Requirement for IT Equipment Varies by Country
In Compliance Magazine recently published a good primer on compliance requirements for IT equipment around the world. Following is a summary of the electromagnetic compatibility regulations. A set of common standards serve as the basis for global EMC regulations: Conducted and radiated emissions are based on CISPR 22 & FCC Part 15 Immunity is based on... Read More
EMC Simulation Best for Determining Relative – Not Absolute – Emissions
For those not based in the Bay Area, we will occasionally cover IEEE EMC Society Santa Clara Valley Chapter events that we think are relevant to Compliance Today readers. After all, the IEEE Santa Clara Valley Section is located in the heart of Silicon Valley, and is the world’s largest IEEE section. Tuesday featured an interesting... Read More
