Powertrain Inverter Modeling Engineer

At Ford Motor Company we believe freedom of movement drives human progress. We also believe in providing you with the freedom to define and realize your dreams! With our incredible plans for the future of mobility we have a wide variety of opportunities for you to accelerate your career potential as you help us define tomorrows transportation.

Electric Vehicle Digital Design (EVDD) is responsible for developing the key technologies and capabilities such as EV platforms batteries emotors inverters charging and recycling to create groundup breakthrough electric vehicles. By joining the best software engineering design and UX talent you will be a part of creating new technologies and concepts that can be applied across the Ford enterprise. Being on the EVDD team means building the future as Fords center of innovation and growth through electric and connected vehicles and services.

The Powertrain Inverter Modeling Engineer will be responsible for developing component and system level traction inverter models to optimize Fords electric powertrain architectures. You will conceptualize and own parametric inverter models that include cost mass loss semiconductor selection and passive component sizing. You will perform detailed inverter level simulation studies interpret the results and select optimal tradeoffs between mass loss and cost based on vehicle level performance metrics. This cross functional role will work closely with electrical mechanical and thermal teams to understand constraints imposed by coupled subsystems and provide quantitative guidance to define power electronics architectures for the next generation of efficient costeffective powertrain platforms at Ford.

What youll be able to do:

• Lead the development of a parametric multiphysics inverter simulation model for use within a larger drivetrain optimization tool
• Estimate inverter switching losses and voltage overshoot from circuit simulations using data from device datasheets and electrical characteristics derived from CAD models
• Develop parametric sizing models for inverter passive components (inductors y capacitors bulk capacitors chokes) to analyze tradeoffs between minimizing drivetrain cost loss and mass
• Collaborate with the inverter team to derive parametric inverter thermal statespace models from detailed FEA/CFD simulations and correlate those models to test results
• Collaborate with the inverter team to define switching loss characterization test plans to gather data for experimentally informed loss models
• Perform and analyze large scale drive cycle simulations to identify active constraints in the inverter design and suggest changes that improve performance and reduce cost while meeting system level requirements
• Analyze the interaction between inverter design control methodologies motor loss and DC bus stability
• Maintain documentation and write unit tests to guarantee correct functionality of custom software tools

The minimum requirements we seek:

• M.S. in electrical engineering with a focus in power electronics and/or semiconductor physics
• Strong understanding of inverter loss sources including semiconductors capacitors inductors bus bars gate drivers and auxiliary circuits
• Experience sizing passive components to meet ripple current ripple voltage bus stability and EMC requirements
• Experience translating semiconductor data sheets and experimental test results into simplified loss and thermal model
• Strong linear systems and numerical methods background
• Experience with software development in MATLAB or a similar technical computing language (Python Julia C)

Preferred Requirements:

• PhD degree in electrical engineering with a focus in power electronics and/or semiconductor physics
• Experience performing circuit simulations with detailed semiconductor models (LTSPICE PSPICE etc.
• Familiarity with interplay between inverter design/control and motor losses EMC/EMI and DC bus stability
• Familiarity using impedance and network analyzers to characterize the frequency dependent characteristics of passive electrical components
• Familiarity with power electronics doublepulse and transient thermal test equipment and procedures
• Experience with objectoriented software development in MATLAB or a similar technical computing language (Python Julia C)

What youll receive in return:

As part of the Ford family youll enjoy excellent compensation and a comprehensive benefits package that includes generous PTO retirement savings and stock investment plans incentive compensation and much more. Youll also experience exciting opportunities for professional and personal growth and recognition.

If you have what it takes to help us redefine the future of mobility we would love to have you join us.
