Solid-state relays: Better reliability in HEVs & EVs with best-in-class isolation technology

00:12:46 | 10 MAY 2022

Learn how capacitive and magnetic isolation are setting a new benchmark for isolation technologies in high-voltage automotive systems and a positive impact on enabling higher reliability for HEV/EV battery management systems, traction inverter and motor control, on-board and off-board charger and more.

In this traning you will learn:

  • What is capacitive and inductive isolation and how they compare to optically isolated solid-state photorelay solutions or electromechanical relays
  • How the new solid-state relay family from TI enables you to improve system performance while saving cost and reducing solution size.
  • Practical solutions to design high voltage pre-charge circuits, active discharge, adjustable gate drive strength, isolation check / insulation resistance monitoring, and more.
