About us

The Power & Electronic Systems Research Team is expanding this year. We team works across several product categories and are involved a range of technologies including power electronics, embedded electronics, sensors and software.  We work very closely with the New Product Innovation (NPI) teams and deliver technologies into new products during the research phase.  A successful candidate will be working to generate new ideas and technologies to enable specific product features, as well as researching into future technologies. 

Some of the technology areas the team covers includes:

  • AC-DC and DC-DC conversion up to 3kW.

  • High speed motor drive design.

  • Lithium-ion battery management.

  • Heater control.

  • Microcontroller selection and software for the above, including control algorithm implementation.

About the Role

We work alongside the mechanical, electromagnetic, thermal and aero/acoustic teams in Technical Research, as well as the Energy Storage team, to help find the best technologies and integration approaches.  The work will involve shorter term projects targeting specific products, alongside longer term research projects to bring emerging technologies into future products.

  • Working with the different sub-teams within Technical Research, as well as NPI, other research groups and development teams to gain an in depth product understanding, while using your expert knowledge of the latest technologies to create innovative systems and solutions and solve complex system level problems.

  • Demonstrate designs are robust and viable for use in product through laboratory testing and driving the team to develop simulations to optimise designs.

  • Ensuring the team generates suitable test specifications to ensure product reliability, safety and robustness. This includes the development of test environments including simulation, emulation and hardware/test equipment interactions.

  • Producing hardware designs and performing review activities (component selection, schematic capture, PCB layout and reviewing of the aforementioned).

  • Ensure electronic requirements and architecture details are documented by the team.

  • Managing technical risks in a project through FMEAs.

  • Assist in producing review packs which typically include concept specifications, requirements and specification documentation, risk registers, FMEAs and design guides when needed.

  • Researching into new and emerging technologies through visiting conferences, trade shows, meeting suppliers, reading papers and patents.

  • Identify emerging IP and ensure inventions are submitted to the IP team.

  • Helping to manage laboratories and assist with risk assessments and ensure best practices for lab safety.

  • Working on multiple, small concurrent projects, supported by several team members all reporting to the Senior Research Manager for the team. 

  • Mentoring staff within the Power Electronics research team to ensure team philosophies and working practices are applied to a project.

Education and experience:

  • BEng/MEng degree in Electrical or Electronic Engineering, or other relevant discipline, or a demonstrable level of industrial experience in a relevant industry.

  • Candidates should be able to demonstrate an ability to research, innovate, as well as being a key contributor to strengthening the culture of innovation within the team and wider department.

  • Applicants should specialise in power electronics for this role and have a broad knowledge of electronics.

Technical knowledge:

Power Electronics

  • Experience in motor inverter design and motor control, particularly brushless DC motors, servo or stepper motors

  • Experience of power converter design.

  • Knowledge of heater control hardware, control schemes and heater protection approaches.

  • General knowledge of power electronic devices, including silicon based IGBTs and MOSFETs through to emerging wide bandgap technologies.

  • Understanding of device characteristics and issues with switching behaviour in real circuits, as well as power switch driver design.

  • Knowledge and experience of using power modules (e.g. drivers and power switches in one device).

  • Thermal management approaches for surface mount and through hole devices.

  • Design of power electronics for <60V battery powered systems and consumer mains voltage systems.

  • PCB layout – size/cost minimisation while achieving layouts for inherently good EMC compliance and thermal design.

  • Device selection - Interpretation of datasheets and knowledge of design methods to confidently select the lowest cost devices while achieving reliability targets.

Control Circuit Design, Techniques and Tools:

  • Excellent understanding of techniques for accurately monitoring small signals in high power, electrically noisy environments.

  • Knowledge of analogue to digital converters, op-amps, comparators, voltage references etc.
