How to design multi-kW DC/DC converters for electric vehicles (EVs)

This eight-part training series will explore how to design multi-kW converters for EVs.

We are all well aware that the demand for electric vehicles (EV) is increasing rapidly. This eight-part training session begins with a description of a typical EV system in part 1. Part 2 is a brief description of how both lead-acid and lithium-ion batteries are charged. Part 3 focuses on the types of power factor and harmonic currents. Part 4 discusses power factor correction (PFC) and the typical boost PFC stage. Part 5 concentrates on the phase shifted full bridge (PSFB) topology, including the reasons why it is used and a detailed description of how it operates. Part 6 dives deep into a PSFB and how it works. Part 7 shows how a high power battery charger can be designed using the UCC28951-Q1 and other automotive grade parts from Texas instruments. Finally, part 8 discusses the role of MOSFET gate drivers in your power system.

At the end of this training series you will:  

  • Have learned about typical EV power systems at the block diagram level
  • Understand some of the reasons why they are designed in this way
  • Know how the Phase Shifted Full Bridge topology is used in EV applications
  • Have a high level understanding of an on-board charger design
  • Understand how gate drivers can improve your power system
