摘要： A gate drive circuit for applying a voltage to a gate of a semiconductor switching device is disclosed. The gate drive circuit includes a gate drive controller that provides voltage commands for operating the semiconductor switching device, a plurality of primary gate resistors coupled between the gate drive controller and the semiconductor switching device, one or more secondary gate resistors connected in parallel with the primary gate resistors, a primary transistor connected in series with each of the primary gate resistors, and a secondary transistor connected in series with each of the secondary gate resistors. Further, one of the primary or secondary transistors receives the one or more voltage commands from the gate drive controller and provides one or more corresponding voltage levels to the semiconductor switching device via one of the primary or secondary gate resistors so as to control the on-off behavior of the semiconductor switching device.

摘要： In one aspect, a method for controlling the operation of switching elements contained within a single-phase bridge circuit of a power convertor may include monitoring gate voltages of a first switching element and a second switching element of the single-phase bridge circuit and controlling the first and second switching elements so that each switching element is alternated between an activated state and a deactivated state. In addition, the method may include transmitting a gating command signal to adjust the first switching element from the deactivated state to the activated state when: a first gate drive command is received that is associated with switching the first switching element to the activated state; a second gate drive command is received that is associated with switching the second switching element to the deactivated state; and the gate voltage of the second switching element is less than a predetermined voltage threshold.
