Abstract:
A driving circuit for an emitter-switching configuration of transistors having first and second control terminals connected to the driving circuit, forms a controlled emitter-switching device having in turn respective collector, source and gate terminals. The driving circuit comprises a driving block coupled between the collector terminal and the source terminal of the controlled emitter-switching device and connected to the first control terminal of the emitter-switching configuration. Further advantageously, the driving block comprises at least one IGBT driving device coupled between the collector terminal and the first control terminal of the emitter-switching configuration and having, in turn, a third control terminal, as well as a driving bipolar transistor, coupled between the collector terminal and the first control terminal of the emitter-switching configuration for controlling a saturation condition of said bipolar transistor of said emitter-switching configuration maintaining a base-collector junction thereof at a voltage next to zero and having, in turn, a fourth control terminal.
