Siemens - Bsm B3 Schematic Work

While Siemens and Delphi both produce BSM B3 modules, they share the same external pinout and general function, making them largely "plug and play" compatible.

The schematic work begins at the input terminals, usually designated as L1, L2, and L3. The "B3" designation implies a 3-phase bridge configuration. Unlike the BSM A3 or A5 modules which utilize thyristors for controlled rectification, many standard BSM B3 schematics depict a diode rectifier bridge topology for uncontrolled rectification, or a hybrid thyristor-diode bridge for reduced inrush currents. siemens bsm b3 schematic work
