Senior Power Electronics Engineer
Dyson offers a unique opportunity for a talented and experienced Senior Power Electronics Engineer in the Motors, Power and Electronic Systems Research Team, within Dyson’s Research, Design and Development (RDD) department; based in Malmesbury, Wiltshire, U.K.
Home to our global Research, Design and Development centre and all of our Commercial functions, Dyson HQ is tucked away in countryside famous for the railway tunnels and bridges of Isambard Brunel, who revolutionised modern engineering. Our secluded location helps us to protect our ideas and stay independent-minded. Yet nearby are the fashionable cities of Bristol and Bath (where a young James Dyson invented cyclone technology). The building is the heartbeat of Dyson. Over 1,500 people, including James himself, spend their days strategizing, inventing technology and telling the Dyson story to the world. From 2016, our HQ will begin doubling its footprint with an ambitious new expansion.
Sometimes, making a technological leap forward means going back to the beginning. Since 1999, we’ve spent £150m building a motor from scratch – small, light and efficient, yet extremely powerful. Our motors are what enable our technology to be different – it’s why they’re protected by 20 to 30 patents. But the next generation demands new directions. Energy storage, robotics, nanotechnology and space-age materials. So our multi-disciplinary team, led by some of the world’s best power electronics engineers, knows that only the most pioneering thinking will do. That’s the Dyson way.
Applicants for this particular role must have directly applicable experience in the aforementioned power electronics areas. The senior power electronics role will involve:
Working with the different research teams to gain an in depth product understanding, while using their expert knowledge of the latest technologies to create innovative power electronics systems and solutions
* The design of motor inverters, device selection, gate drive design, operating and protection strategies.
* The design of power supplies for a broad spectrum of potential applications and power ratings.
* Ensuring designs can comply with relevant EMC/EMI standards and modifying the design where needed to ensure this is the case.
* Specification of associated passive components, contactors, cables, connectors and fusing.
* Thermal management of power electronics systems.
* Design of both mains and battery powered electronics to meet global requirements. Whilst the Power Electronics team is responsible for supporting new products at initial design stages, a key focus for any successful applicant will be to research into new technology and look at innovative ways of incorporating this into future products. As a senior employee, a successful applicant will be expected to:
* Develop the concept, proving key technologies and demonstrating the system feasibility.
* Demonstrate designs are robust, cost effective and fit for purpose for a high volume manufacture environment, through detailed laboratory testing, simulation and analysis.
* Initiating the production intent solution and developing suitable documentation prior to handover to the development teams.
* Take technical responsibility for the power electronics content of a project. This may expand to the responsibility for multiple, small concurrent projects, supported by a number of team members reporting to the Power Electronics Technical Leader.
* Assist in the personal development of junior team members.
Education and experience:
PhD degree in Electronic Engineering or other relevant discipline with a demonstrable level of industrial experience.
Minimum technical knowledge:
* Excellent general knowledge of power electronic devices, including silicon based IGBTs and MOSFETs through to emerging SiC / GaN based technologies.
* Understanding of device characteristics and issues with switching behaviour in real circuits.
* Proven experience in motor inverter design and motor control, particularly gate drive design to component level.
* Device selection - Interpretation of datasheets and knowledge of design methods to confidently select the lowest cost devices while achieving reliability targets.
* Power electronics layout for best compromise between good switching performance, cooling, cost and size.
* Thermal design
* Design and specification of passive components
* Schematic capture using Altium Designer, Mentor Graphics or other main stream tools
* Use of SPICE based simulation tools such as Simetrix
* System level modelling tools such as Matlab, Simulink and PLECS
* FlowTherm or similar thermal modelling packages
* Design calculation tools such as Mathcad, Matlab, Excel
* Circuit simulation and design tolerance analysis
* Robust design including FMEA techniques
* Good quality engineering process understanding and appreciation
* Design for high volume manufacture
* Mains and DC equipment
* PCB layout – size/cost minimisation while achieving layouts for inherently good EMC compliance and thermal design
* Experience of analogue circuit design (e.g. signal amplification and conditioning for feedback signals from power electronic hardware to microcontrollers for example) is desirable.
