ABSTRACT:
A driving circuit is provided for a control terminal of a bipolar transistor in an emitter-switching configuration. The emitter-switching configuration is between a resonant load and a voltage reference. The driving circuit includes at least one capacitor between the control terminal of the bipolar transistor and the voltage reference. The driving circuit further includes an additional resonance capacitor between a collector terminal of the bipolar transistor and a circuit node, a first diode between the circuit node and the control terminal, and a second diode between the circuit node and the voltage reference.
