WebSep 2, 2012 · Torque controller. For four-quadrant operation two thyristor bridges are used as shown in Figure 19.31 (b). Both bridges can apply positive or negative voltage to the motor, but the positive bridge can only supply positive current and the negative bridge negative current. Therefore the positive bridge conducts when positive torque is required ... WebWhat is a Bidirectional Switch. A bidirectional power switch (BPS) is an active switch with bidirectional current flow capabilities when it operates. Otherwise, if it turns off, the device, called a four-quadrant switch, provides bidirectional voltage blocking. The BPS performs these operations through its MOSFETs or IGBTs implementation.
