Event description

Description

Description

This course will cover design to meet the compliance requirements of the European EMC Directive, as well as other commercial and military requirements. Good EMC design gives you a product that is more reliable and better fitted for its environment. The course is structured to achieve the maximum learning potential from a combination of tutorial and case study exercises. It emphasises the underlying physics of interference generation and coupling and how it affects design methods, without resorting to complex mathematics.

Who should attend

Electronic product designers and design managers: a basic knowledge of electronics is assumed. The course will be of particular interest to design engineers in industrial, medical, transport, telecomms, IT, consumer, marine and military sectors who have to meet EMC requirements as part of their project specification. It will help them deal with the technical and compliance aspects of EMC, as well as avoiding EMC-related design mistakes that disrupt project timescales and budgets.

Course Content

  • Day 1 – Introduction and theory

    • Introduction: Why EMC? | the definition of EMC | the various phenomena | EU Directives | military and aerospace requirements | the standards regime | standards generating bodies | military/aerospace versus commercial | content of the most common test standards
    • Principles of interference coupling: using the dB | frequency versus time domain | coupling modes | electric, magnetic and electromagnetic fields | transmission lines | ground as a current return path | control of loop area

    Day 2 – Mechanical, PCB and cables

    • PCB layout and grounding: track impedance | proximity of return path | gridded and ground plane layouts | current flow in a ground plane | the effect of discontinuities | optimum ground and power plane configurations | layer stack-up and edge effects - interface layout and grounding | grounding hardware | heatsinks and thermal issues
    • Cables and connectors: unscreened cables: twisted pair, ribbon | cable balance and LCL | modes of propagation | screen function and transfer impedance | the effect of the connector
    • Shielding: theory of reflection and absorption | effect of apertures and seams, hatches and doors | enclosure resonance | conductive gaskets | conductive coatings and shielded windows | partitioning shielded enclosures

    Day 3 – Electronics

    • Filtering and suppression: Filter configuration and layout | component imperfections | special components | ferrites on cables and within the circuit | I/O filtering and isolation | supply filtering | choice and use of transient suppressors | contact supporession
    • Power switching circuits: Emissions from switching circuits | coupling paths | differential and common mode sources | construction and circuit techniques: snubbers, transformers, heatsinks
    • Digital and analogue circuit design: Clocks, transmission line matching, power rail decoupling | logic circuit immunity: timing and logic threshold constraints, transient susceptibility and the watchdog, defensive programming | analogue circuit immunity: bandwidth, linearity and dynamic range, balance
    • Wrap up and final discussion.
