Automotive
On Board Charger for Electric Vehicle
The panel shows the main ST devices that can be part of an On Board Battery Charger (OBC) system for an electric vehicle from power devices to control devices 1KW SMPS digitally controlled multiphase Interleaved converter using STNRG388A The STNRG388A power conversion dedicated peripherals (SMEDs) offer the flexibility to drive the interleaved power stages while guaranteeing the correct phase realignment during the activation and deactivation of each stage.
The architecture is based on a multiphase interleaved DC/DC converter using the half bridge SAB (“Single Active Bridge”) topology supporting more than 1000 W of power.
The interleaved topology balances the power through 3 parallel stages. Also, the solution delivers high efficiency during the whole load range by enabling one, two or three stages depending on the load.
