摘要： A system and method of discharging a bus capacitor of a bidirectional matrix converter of a vehicle are presented here. The method begins by electrically shorting the AC interface of the converter after an AC energy source is disconnected from the AC interface. The method continues by arranging a plurality of switching elements of a second energy conversion module into a discharge configuration to establish an electrical current path from a first terminal of an isolation module, through an inductive element, and to a second terminal of the isolation module. The method also modulates a plurality of switching elements of a first energy conversion module, while maintaining the discharge configuration of the second energy conversion module, to at least partially discharge a DC bus capacitor.

摘要： Systems, apparatus, and methods are provided for discharging a voltage bus using a transistor. An exemplary gate drive circuit associated with the transistor includes a pulse generation module having an input and an output and a switched capacitance arrangement coupled between the output and a reference voltage node. The pulse generation module is configured to generate a voltage pulse at its output in response to a control signal at the input. In one embodiment, the control signal results in the voltage pulse having a duty cycle that operates the transistor associated with the gate drive circuit in a linear mode when the switched capacitance arrangement is activated.
