Watch this 1-hour, on-demand webinar to learn the basics of power subsystems in electric vehicles (EV) and how high voltage auto-grade power MOSFETs from STMicroelectronics can optimize their efficiency.

Part of the STPOWER portfolio, ST's high voltage power MOSFETs offer breakdown voltages from 400 V to 1200 V and benefit from ST's MDmesh™ super-junction technology to achieve robust performance and increased power density.

The session begins with a discussion of MDmesh technology and roadmap, followed by the positioning of silicon MOSFETs in EV power electronic subsystems. We then explore ST's range of automotive-grade discrete & integrated MOSFET solutions and advanced packaging technology.

By the end of the session you will have a good understanding of electric vehicle power electronic subsystems, and the performance advantages of using MDmesh super-junction MOSFETs in power designs for EV on-board chargers (OBC), battery management systems (BMS), and high-voltage DC-DC converters.

You will learn:

  • About the latest in ST super-junction MDmesh MOSFET technology and product evolution
  • How MDmesh MOSFETs enable the design of highly efficient converters for electric vehicles
  • The fundamentals of EV power electronics subsystems (OBC, BMS, high voltage DC-DC)
