TTI IP&E – Europe, in collaboration with Schaffner, part of TE Connectivity, announces its joint commitment to support engineers in navigating the impending extended electromagnetic compatibility (EMC) regulations, which will soon apply down to 9kHz.
These new regulations are set to have a substantial impact on the EMC landscape. They will be critical for ensuring compatibility, particularly with the rise of powertrains and interfaces connected to the grid amidst a major energy transition towards increased electrification and sustainability.
The forthcoming regulations will necessitate significant adjustments for existing product families and require new product developments to incorporate these standards from the outset. While some EMC product standards, such as FCC Part 15 for intentional and unintentional radiators and CISPR-11 and CISPR-22 for radiated emissions, already specify limits below 150kHz, the broader harmonisation process will see generic standards change first, followed by product-specific standards. This means that all new products will need to comply with the new version once it is in place. Products already available on the market must also comply, regardless of their development date. TE recommends that engineers initiate discussions and activities promptly to avoid future delays, beginning with the evaluation and assessment of new equipment designs through pre-compliance measurements against draft standard limit levels.
TE offers a portfolio of magnetic solutions that address both standard and customised EMC and power quality needs. TE’s expertise ensures a smooth and compliant transition towards these extended regulations. The company provides comprehensive, end-to-end support, encompassing design consultation, in-situ measurement, testing, and ongoing assistance for seamless integration and long-term system stability.
Engineers can benefit from TE’s passive filter solutions and its ongoing work on innovative active filter solutions. Addressing the cost implications of the new 9kHz regulations, the company emphasises that these can be mitigated by integrating adequate filter solutions from the initial stages of product development. While conventional EMI filters can reduce emissions, they can also cause resonance effects, increasing noise and filtering costs, thus necessitating expert guidance to balance compliance and cost-effectiveness.
For electric vehicle (EV) charging equipment, which represents a critical focus application in the electrified future, TE provides specialised filtering solutions. For AC charging applications, a broad portfolio of single-phase and three-phase AC EMC filters is available, with current ratings ranging from 1 to 100A for single-phase systems up to 520VAC, and from 3A to 2300A for three-phase systems up to 690VAC (with HV versions reaching 760VAC), offering standard to very high attenuation levels.
For DC charging stations, TE offers robust DC EMC filters, including the EVX series, specifically designed for EV applications. These filters cater to high current demands from 150 to 1600A (or up to 2300A broadly for DC systems) and high voltage requirements, up to 1500VDC, with options for low leakage current.
To verify product compliance, engineers must conduct adequate tests and measurements starting from 9kHz. TE supports these activities, offering modern test facilities and measurement know-how at its own locations, or supporting external test houses. Most common testing equipment, such as artificial mains networks and EMI receivers, is already capable of testing at 9kHz.
Markus Lorenz, Director Industry Marketing Industrial, TTI, Inc. – Europe, states: “The rapid pace of electrification demands robust solutions for EMC. Our partnership with Schaffner, part of TE Connectivity, empowers our customers with unparalleled access to industry-leading expertise and innovative filter technologies. This collaboration is crucial in helping them not only meet the challenging new 9kHz EMC regulations cost-effectively but also to ensure the reliability and performance of their critical systems in an increasingly connected and electrified world. We are committed to guiding our customers through this transition seamlessly.”
Through this strategic collaboration, TTI and TE are ready to enable engineers to achieve a smooth, compliant, and cost-effective transition towards the new extended EMC regulations, safeguarding product performance and reliability in diverse application environments, including the rapidly expanding EV infrastructure.
