摘要： A method for controlling a modular converter with a plurality of converter modules includes: selecting possible future switching sequences of the converter based on an actual converter switching state; predicting a future current trajectory for each switching sequence based on actual internal currents and on actual internal voltages; and determining candidate sequences from the switching sequences, wherein a candidate sequence is a switching sequence with a current trajectory that respects predefined bounds with respect to a reference current or, when a predefined bound is violated, moves the current closer to such a predefined bound. The method includes predicting future module voltages for each candidate sequence; evaluating a cost function for each candidate sequence; and selecting the next converter switching state as a first converter switching state of a candidate sequence with minimal costs.

摘要： Methods, systems, circuits, and devices for power-packet-switching power converters using bidirectional bipolar transistors (BTRANs) for switching. Four-terminal three-layer BTRANs provide substantially identical operation in either direction with forward voltages of less than a diode drop. BTRANs 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. BTRANs are driven into a state of high carrier concentration, making the on-state voltage drop very low.
