Selection Notes

The 2-quadrant B6C circuit uses a single three-phase bridge, so this converter drives the load in one direction without regenerative braking; choose it over a 4-quadrant unit when the application only needs to motor, not brake through the armature. At 104 A input and 125 A output, it is the highest-current variant in this group.
