Tiny power box

Start: Q4 2018

Objective

To design a highly compact, bi-directional 7-11 kW converter as an onboard charger and to use this converter as a “vehicle” for developing a holistic design-by-simulation workflow.

The main challenges and topics of investigation are:

  • To find a circuit topology/control/design combination capable of breaking state-of-the-art power density and satisfying industry legal standards.
  • To build a proof-of-concept demonstrator using advanced components and integration technology; utilising the expertise of our industrial partners representing the whole power electronics value chain.
  • The novel simulation workflow should fill a gap in the current design process by including critical physical affects not typically included in circuit simulation, i.e. temperature, EMC and lifetime.
  • Developing efficient data exchange between software packages for the co-simulation workflow. Workflow to be used in this and future SAL projects, with intention of sharing with industrial partners.

Expected results

  • A proof-of-concept demonstrator meeting legal industry standards and improving state-of-the-art power density.
  • A holistic simulation workflow that couples open-source and/or industry standard software, allowing easy penetration into the wider power electronics industry.
  • Simulation verification using proof-of-concept demonstrator.
  • Clear path for introducing lifetime prediction into simulation workflow using component models from partners.
  • Architecture and simulation workflow to be available for future converter designs.
