摘要： A driver for a power transistor switch comprising a FET complementary output stage which is driven by another FET complementary pre-driver stage which is further driven by an input-buffer and level-shifter stage. The pre-driver stage includes a current-limiting and cross-delaying circuit which is inserted in between drains terminals of a complementary FET pair. The current-limiting and cross-delaying circuit limits shoot-current at the pre-driver stage; and in conjunction with the FET pair and the input-buffer and level-shifter stage, it is adapted to delay turning on one complementary output FET until after the other complementary output FET is turned off, thereby preventing cross conduction at the output stage.

摘要： An apparatus and methods to fabricate the apparatus for balancing a string of N series-connected electrical energy units (such as battery cells or modules) comprising: a transformer with a magnetic core and N windings; N switch circuits; N driver circuits, each driver circuit operable to turn ON/OFF a respective switch circuit in a discharging or charging or idling configuration; and a controller circuit. In a novel way, the controller circuit selects each electrical energy unit for discharging or charging or idling, and controls simultaneously coupling all selected-for-discharging electrical energy unit(s) to respective winding(s) in discharging configuration(s) for a first period of time to simultaneously energize the respective winding(s); then immediately or after a short delay, the controller circuit controls simultaneously coupling all selected-for-charging electrical energy unit(s) to respective winding(s) in charging configuration(s) for a second period of time to be charged with respective induced current(s).
