Selecting Op Amps for HEV/EV Powertrain Systems Part 2
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
