Dyson offers a unique opportunity for a talented and experienced Power Electronics Engineer in the Technical Research Team, within Dyson’s Research, Design and Development (RDD) department; based in Malmesbury, Wiltshire, U.K.
At Dyson we are encouraged to think differently, challenge convention and be unafraid to make mistakes. We’re creative, collaborative, practical and enthusiastic, but most of all we’re hugely passionate about what we do. We are looking for individuals who wish to invent, design and develop leading products for the global market. By working in our world class Research Design and Development department, these individuals have the opportunity to work alongside other leading technical specialists and highly motivated creative people, to create products which fulfil our ambition of being truly different and better than our competitors.
Dyson products strive to be at the leading edge of technology. Through unique strategic partnerships with global top universities and leading businesses, we gain foresight of up and coming technologies. The technical research team aims to exploit this knowledge to design state-of-the-art products allowing us to differentiate our products from the competition and be ahead of the times. Dyson is expanding into several new and exciting product categories and is positioning itself as a technology company, confirmed by the release of the 360 Eye robotic vacuum cleaner, the connected Pure Cool Link purifier, the Supersonic hairdryer and investments in Sakti3 solid state battery technology. Successful applicants for this role will be part of the team driving these products and others forward.
Applicants for this particular role must have some experience in one or more of the aforementioned power electronics areas. The power electronics role will involve: •Working with the different product teams to gain an in depth product understanding, while using knowledge of the latest technologies to create innovative power electronics systems and solutions •The development of battery management systems and assessment of alternative battery management solutions and topologies depending on the product requirements •Ensuring battery management systems meet regulatory and company requirements for safety •The design of motor inverters and control for brushless DC, servo and stepper motors •The design of heater control hardware and associated protection hardware •Power converter design •Ensuring designs can comply with relevant EMC/EMI standards and modifying design where needed to ensure this is the case •Thermal management design of power electronics systems •Design of both mains and battery powered electronics to meet global requirements.
Education and experience: •Minimum BEng/MEng degree in Electronic Engineering or other relevant discipline Minimum technical knowledge: •Power Electronics: ◦General knowledge of power electronic devices, including silicon based IGBTs and MOSFETs through to emerging GaN based technologies ◦Understanding of device characteristics and issues with switching behaviour in real circuits as well as power switch driver design ◦Device selection - Interpretation of datasheets and knowledge of design methods to confidently select the lowest cost devices while achieving reliability targets ◦Knowledge and experience of using power hybrid modules and power SoC modules (e.g. drivers and power switches in one device) ◦SMPS and linear regulator power supply design for digital and analogue electronic systems ◦Experience in motor inverter design and motor control, particularly brushless DC motors, servo or stepper motors desirable. Design Tools: ◦Schematic capture using Altium Designer, Mentor Graphics or other main stream tools ◦Use of SPICE based simulation tools such as Simetrix and LTspice •Experience of analogue circuit design (e.g. signal amplification and conditioning for feedback signals from power electronic hardware to microcontrollers for example) . •Experience of programming microcontrollers, such as Cortex M devices is desirable. Design Techniques: ◦Circuit simulation and design tolerance analysis ◦Robust design including FMEA techniques ◦Good quality engineering process understanding and appreciation
