Application / Career / Impact Opportunities A SMALL selection of exciting areas
Aerospace
Impact of Power Electronics Future Power Electronic hardware for airliners will be progressively more power dense than current technology. Power electronics..... are on a steep curve of performance and cost improvement. The power electronics of just 10 years ago were too large and heavy.

Aerospace Opportunities As new designs of civil airliner are launched into fleet service between 2015 and 2025, the annual global market for the power electronic content of each shipset will be between around 1225M at today s values. Assuming a successful UK National Strategy is effective in supporting the UK share of the global market at 15% to 20%. Typical annual turnover per employee on OE (Original Equipment) in UK Aerospace is ~ 213k. Core Jobs in high added value manufacturing created/retained will be around 1000. 3100 other jobs will be indirectly supported elsewhere in UK manufacturing. Significant degree of Vertical Integration of Technical Specialist & Sub-Contractors in the UK based Supply Chain could considerably increase this total. 19

Incremental change is not enough Theory induced blindness inhibits radical innovation Understand limitations Challenge convention Strive to make things better Multi-disciplinary Teamworking is vital
Cross Sector Opportunities Cross Sector Visibility has decreased Specialist Conferences, Journals & Forums restrict view Power Electronics is in many respects mature - High Reliability has been achieved in many very demanding applications, and this experience should be built on Systems issues (eg EMC) can vary between sectors but the Physics can t! Vocabulary can be an issue
Vocabulary Vocabulary is one of the most important aspects of effective working but rarely gets discussed I used to run a training session for cross functional teams
Clearly State Objectives of the Project Q: In what Language should the project objectives be written? Simple - Project Charter User Language - User Requirement Specification Design Engineers Language - Functional Requirement Specification Marketing Language - Marketing Plan Accountants Language - Business Plan Manufacturing Language - Manufacturing Plan
BUT that is only part of the problem Power Semiconductor suppliers and users are different animals!!
