Wiltshire

Our innovative technology client is seeking a Senior Power Electronics Engineer - Motor Drive to join their research team to be a part of concept development of new products within the business.

Accountabilities
The successful applicant for this role will be part of the team designing the next generation of power electronic systems for our products. The power electronics team in Technical Research is responsible for a number of disciplines, including: 
Motor inverter hardware for motor systems that can operate in excess of 100,000rpm 
Power supply design - DC-DC and AC-DC designs 
Battery management systems - design of Lithium-Ion battery management systems for a variety of products and cell pack structures, as well as development of new battery management system for emerging cell technologies 
Charger design 
Heater control systems and protection 

The Senior Power Electronics – Motor Drives role will involve: 
The design of motor inverters and control for brushed and brushless DC, servo and stepper motors 
Working with 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 
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 compliance standards and safety requirements 
Use of electronic simulation tools to gain detailed understanding of circuit behavior 
Creating electronics schematics and PCB layouts that meet product requirements and provide functional product prototypes 
Strong lab skills to build and test prototypes with minimal supervision 
As a Senior Power Electronics Engineer, the successful applicant will be expected to: 
Develop a power system concept, prove key technologies and demonstrate the system feasibility 
Produce clear, well written documentation prior to handover to the development teams 
Demonstrate designs are safe, robust, cost effective and fit for purpose for a high volume manufacture environment, through detailed laboratory testing, simulation and analysis.

Skills
Education and experience: 
Minimum BEng/MEng degree in Electrical & Electronic Engineering or other relevant discipline 

Minimum technical knowledge: 
Power Electronics: 
Experience in motor inverter design and motor control, particularly brushless DC motors, servo or stepper motors 
General knowledge of power electronic devices, including silicon based IGBTs and MOSFETs and wide bandgap 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 

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 
Design calculation tools such as Mathcad, Matlab, Excel. 
Design Techniques: 
Circuit simulation and design tolerance analysis 
Good quality engineering process understanding and appreciation 
PCB layout – size/cost minimisation while achieving layouts for inherently good EMC compliance and thermal design. 

Essential behavioural skills: 
Good analytical ability and attention to detail 
Ability to communicate appropriate, concise and accurate information in written and verbal format 
Ability to adapt or generate imaginative and innovative ideas, in line with core values 
Ability to multi-task and plan effectively when working with a variety of project teams.
