Device in an emitter-switching configuration with means for recovering the electrical charge during turning off

摘要

A device in an emitter-switching configuration comprises a high-voltage transistor having a first terminal connected directly to a first power terminal of the device, a control terminal connected to a control terminal of the device, and a second terminal. The device also includes a low-voltage transistor having a first terminal connected directly to the second terminal of the high-voltage transistor and a second terminal and a control terminal which are connected directly to a second power terminal and to the control terminal of the device, respectively. A circuit portion is provided for recovering an electrical charge discharged from the control terminal of the high-voltage transistor to the second terminal of the low-voltage transistor during the turning-off of the device.
