Use new technologies and grow in global markets
Valuable information for electronic, mechanical and PCB designers; safety engineers; design, production and QA managers; to help them comply with legal requirements, remain competitive and reduce financial risks as electronic technologies advance.
The recent reliability problems experienced by speed detection cameras Sydney’s train system and city buildings underscore the importance of good EMC design.
This series of stand-alone ½, 1 and 2-day courses, new (or updated) in the southern hemisphere, describes practical techniques for saving time and cost and reducing non-compliance and financial risks, for new products and systems including major projects such as transportation systems, buildings and industrial plant.

A practical grounding in the EMC techniques that technology developments have made essential for time-to-market, compliance, reliability and low warranty costs. This course is highly recommended for those involved in any aspect of the design or testing of electrical/electronic products, systems and installations.
This is based upon the course that Keith teaches to post-graduate students on the Electronic Instrumentation Systems M.Sc. course at UMIST (University of Manchester Institute of Science and Technology), U.K.

EMC design for RF emissions/immunity in switch-mode power conversion
(e.g. power supplies, UPSs and inverter drives)
½ day
Switch mode power conversion using pulse-width-modulation (PWM) is used in off-line a.c.-d.c. power supplies and in d.c.-a.c. inverters for uninterruptible power supplies (UPSs) and variable-speed a.c. motor drives.
Their use is increasing as manufacturers try to save cost and increase energy efficiency – but they can cause serious emissions problems at up to 1000 times their switching frequency. And if they suffer interference the result can be catastrophic damage.
This course describes the major issues and describes how to deal with them in practice.
Relevant for: All electronic designers and their managers, in all industry areas including: CE/C-tick/FCC compliance, electrical authority, automotive, medical, consumer, household, IT, industrial, rail, aerospace and military.

Presented by: Keith Armstrong
Well-known author and expert in cost-effective EMC and safety management and design.
A practising EMC and electronic design engineer and Chairman of IEE’s Working Group on EMC and Functional Safety.

Use new electronic technologies and compete effectively in global markets
Integrated circuit (IC) and power-switching semiconductor silicon feature sizes continue to shrink year-on-year, providing huge benefits for product and system functionality and cost. The present challenge is to use ICs with feature sizes down to 90nm, and silicon technologies at 65 and 45nm are already being developed.
There are very powerful economic drivers forcing us to use ICs with ever-smaller feature sizes, but the inevitable downside of this is continually worsening signal integrity and EMC performance, for both emissions and immunity.
EMC emissions at high frequencies are increasing, and susceptibility is worsening. The parallel trend to higher clock and power-switching frequencies also increases emissions, whilst the trend to lower d.c. voltages and the use of co-located WLAN transmitters also worsens susceptibility.
Existing products are not exempt, as IC manufacturers convert their existing product lines to use ‘smaller’ silicon technologies, to make more money. This is known as a ‘mask shrink’ or ‘die shrink’ and has cost some manufacturers millions of US dollars in re-engineering existing products because of the EMC problems it causes.
The added functionality and lower cost of the new IC and semiconductor devices creates a great many exciting new possibilities for products and services. This encourages the use of modern electronic technologies in areas where there is little or no relevant experience, increasing risks.
The increase in risks is especially true as modern electronics penetrate safety-related areas from vehicles and transport infrastructure through industrial automation, medical and healthcare, to household appliances and toys.
All this creates increasing challenges to development costs, development timescales, regulatory compliance costs, reliability, warranty costs, user safety, exposure to product liability claims and other financial risks.
For a company to benefit from modern electronic technologies requires its electrical, mechanical and PCB designers, plus its design, production and QA managers, to keep updating their knowledge of practical techniques to control signal integrity and EMC – exactly what these courses provide.
