"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.
