 EMC UK 2018 Training Conference

Tuesday 25th September 2018 Training

Registration & Refreshments 08.30.

Session One 09.00 to 10.30

Everything we need to know in 2018 about... Shielding 
Keith Armstrong

 Shielding is the complementary part to filtering and transient suppression, and in 2018 has to deal with many GHz. We no longer always need metal or metallised plastic boxes: modern shielding can often be small, light, low cost and – if needed at all – can be simply a part that is assembled on the PCB.

10.30 to 11.00 Refreshments in the Exhibition Hub & Exhibition Visit

Session Two 11.00 to 12.30

Everything we need to know in 2018 about... Filtering and suppression 
Tim Williams

Filtering is the complementary part of shielding. Supply, analogue and digital I/O interfaces have different requirements for filtering and transient suppression and we cover the relevant design principles for choosing the right configuration in each case.

12.30 to 14.00 Lunch in the Exhibition Hub & Exhibition Visit

Session Three 14.00 to 15.30

Everything we need to know in 2018 about... PCB layout for EMC  
Keith Armstrong

The most cost-effective place to avoid EMC problems is in the PCB, but good PCB layout for EMC changes more rapidly than any other aspect of good EMC engineering, and in 2018 has to deal with many GHz. If PCB EMC design practices haven’t been reviewed against the state of the art since 2014 or 2015, it is important that we do so now.

Wednesday 26th September 2018 Training

Registration & Refreshments 08.30.

Session One 09.00 to 10.30

Everything we need to know in 2018 about... EMC compliance tests   
Tim Williams

When our product goes to a test house it will be put through a series of EMC tests. 
We describe each of the major emissions and immunity tests, and what they mean for design.

10.30 to 11.00 Refreshments in the Exhibition Hub & Exhibition Visit

Session Two 11.00 to 12.30

Everything we need to know in 2018 about... EMC pre-compliance testing  
Keith Armstrong

Before we send a product to an EMC Test House (if we do, it’s not mandatory for the EU) we should already know it is likely to pass. Modern low-cost test instruments help save huge amounts of time and money, and some of them will be shown doing exactly that.

12.30 to 14.00 Lunch in the Exhibition Hub & Exhibition Visit

Session Three 14.00 to 15.30

Everything we need to know in 2018 about... Cabling practices for EMC  
Tim Williams

Cables are a major coupling route for interference into and out of a product. We discuss the trade-offs that must be made in the choice between screened and unscreened cables, and show the important constructional and termination aspects in the use of screened cables.

EMC UK 2018 Technical Conference

In 2018 we plan to run the Technical Conference, the outline programme is as follows:-

Tuesday 25th September 2018 Technical Conference

Registration & Refreshments 08.30.

Session One 09.00 to 10.30

Antenna & Wireless Integration                                                                                     Chairman - Paul Duxbury - MVG

Over the last few years, more and more everyday electrical and electronic products have started to incorporate antennas to allow them to have some form of wireless connectivity. The development of the Internet of Things, and the introduction of more and more ‘smart’ products, will see this trend continue and accelerate. Likewise, products which have traditionally contained antennas and wireless capabilities, such as cars and mobile phones, are increasingly having more and more antennas incorporated into their design. This is meaning that getting their design right, both the antenna and the rest of the electronics, to ensure that they can coexist and not cause interference is becoming an increasingly major part of the design process.

CE marking and product performance issues when collocating multiple radio transceivers

Speaker - Charlie Blackham – Sulis Consultants

  • EMI coupling of clocks and other signals causing receiver blocking
  • Antenna inefficiency
  • Receiver overload due to co-located transmitter

 

10.30 to 11.00 Refreshments in the Exhibition Hub & Exhibition Visit

Session Two 11.00 to 12.30

Wireless Power Transfer, including EM fields and  Human Health                                         Chairman - David Taylor

WPT-EV is a serious threat to LF/MF broadcasting and to the HF amateur service in general. Unlike low power commodity WPT electrical products, it is a high density, high power and high signals occupancy system operating at up to 22 KW (90 KHz nominally) in a domestic urban environment. EMC Standards covering design and implementation are being developed, however the likelihood is that the time honoured broadcast protection limits will be seriously surpassed in radiated emissions.

12.30 to 14.00 Lunch in the Exhibition Hub & Exhibition Visit

Session Three 14.00 to 15.30

Test & Troubleshooting                                                                                                       Chairman - Richard Marshall 

Analysis of the effects of the Electromagnetic Fast Transient test                                                Tim Williams - Elmac Services

The EFT/Burst test of IEC 61000-4-4 is a good test of the susceptibility of a product to switching transients. But it is also often found to provoke susceptibilities, particularly in digital equipment, which can be hard to fix. A typical reason for this difficulty is that the actual coupling paths followed by the transient disturbances are obscure. This paper shows how you might analyse such paths and offers some measurement results on a simple unit which illustrate the analysis.

Characterisation of emission from mains cables                       Richard Marshall and John Woodgate - Consultants

Established methods for managing mains cable termination ignore the conversion of differential-mode (DM) emissions to common-mode (CM) and the resulting radiation.

Radiated measurements from mains cables are inaccurate and non-reproducible if there is a significant DM conducted emission (non-radiating) and the cable is terminated by a network with impedance unbalance that creates CM (radiating) emission. Current UK work in CISPR towards an improved measurement procedure will be described together with new LISN hardware and illustrated by simulations and simplified measurements.

VDSL radiation and its signal characterisation                                                                           Dr Martin Sacs - RSGB

Often VDSL2 broadband interference goes unrecognised since it looks like background noise. This is not surprising as any characteristic of a communication system that is distinguishable from white noise represents inefficiency in the use of the spectrum.  To detect modern digital communications signals such as VDSL2 one needs to understand the coding techniques used and any aspects of them which are less random. Graphical analysis software has been developed that identifies, isolates, and measures these signal components even at poor signal/noise ratios.

Wednesday 26th September 2018 Technical Conference

Registration & Refreshments 08.30.

Session One 09.00 to 10.30

Specifying Electromagnetic Compatibilty (EMC) and other Electromagnetic Effects                                                                                                                                                                                              Chairman - Prof Ian MacDiarmid

Many prime contractors or designers and developers of complex systems do not design and develop the equipment which they integrate into the final system. As such they have to develop specifications which control all the electromagnetic effects which the equipment has to cope with. These include the traditional EMC susceptibility and emission requirements. In addition, there are a growing number of other electromagnetic effects, including electrostatic charging, induced effects of Lightning, intentional electromagnetic interference etc.

 

Towards a risk-based systems engineering approach for automotive EMC engineering

                                                                                                                             Alastair Ruddle - HORIBA MIRA Limited

The range and complexity of technologies that are now being deployed in modern vehicles are increasing at an unprecedented rate. Furthermore, the pace of change is becoming so fast that standardization activities struggle to support these on-going developments. As the role of the driver/operator is progressively removed from vehicle control, the electronic systems that replace the human inputs will need to provide extremely high levels of dependability in order to ensure the public acceptability of these technologies. Thus, the electronic systems of future vehicles, as well as the intelligent transport systems that they interact with, will need to be designed to ensure a high degree of resilience to a wide range of threats. The adoption of more robust systems engineering practices and a risk-based approach will be key to meeting the challenges of future automotive EMC engineering. This paper outlines the elements of a unified risk-based approach to support the development of future vehicles that are highly resilient to environmental and criminal threats, thus ensuring acceptable levels of functional safety, safety of the intended functionality, cyber security and mission-critical functionality.

10.30 to 11.00 Refreshments in the Exhibition Hub & Exhibition Visit

Session Two 11.00 to 12.30

EMC Design Tools, this session to include simulation, system integration & diagnosis.           
                                                                                                                                           Chairman - Dr John F Dawson

Design of equipment to meet EMC specifications is still a challenge. Desktop computers are now powerful enough to allow full wave electromagnetic solvers to be used for many practical problems. Signal integrity and PCB layout analysis is available with PCN layout tools, using the tools for practical problems & understanding the results is still challenging for a design engineer. In addition, there are many attempts at providing simplified design calculators to estimate signal integrity, shielding, filtering, decoupling etc. available in EMC text books. In this session we aim to illustrate the application and pitfalls of these tools.

We invite contributions which provide information of interest to practical engineers on the use of simple or sophisticated design tools for assessing the performance from components to systems.
