Abstract
Methods, systems, circuits, and devices for power-packet-switching power converters using bidirectional bipolar transistors (B-TRANs) for switching. Four-terminal three-layer B-TRANs provide substantially identical operation in either direction with forward voltages of less than a diode drop. B-TRANs are fully symmetric merged double-base bidirectional bipolar opposite-faced devices which operate under conditions of high non-equilibrium carrier concentration, and which can have surprising synergies when used as bidirectional switches for power-packet-switching power converters. B-TRANs are driven into a state of high carrier concentration, making the on-state voltage drop very low.
