Zusammenfassung:A power stage includes a power transistor and a driver, the power transistor comprising a collector, a gate and an emitter and being configured to change over from a saturated state to an off state and vice versa in accordance with a control from the driver, the power stage comprising a resistor Rg positioned between the driver and the gate, the power stage comprising a circuit for compensating for delays that is positioned in parallel with the resistor Rg, comprising: a circuit for compensating for turn-on initialization delays, which is configured to divert the current from the resistor Rg when a saturation of the power transistor is initialized, a circuit for compensating for turn-off initialization delays, which is configured to divert the current from the resistor Rg when a switching-off of the power transistor is initialized, a circuit for compensating for delays that is configured to divert the current from the resistor Rg when the power transistor is close to the saturated state.
