Date: May 3, 2017

This presentation will focus on the voltage and current monitoring solutions within HEV/EV system – specifically on overcoming the challenges of high voltages and maintaining an isolation barrier. Afterwards, we will discuss specific op amp parameters to consider for monitoring within the on-board charger (OBC), battery management system (BMS), DC/DC converter, and inverter end equipments.

The sub circuits we will walk through are

  • In-line current sensing
  • low-side current sensing
  • high-side current sensing
  • difference amplifiers
  • resolver sensor interface
