Abstract

A driver circuit for switching edge modulation of a power switch. The driver circuit includes a first driver circuit input including a downstream input node, and a power switch including an upstream first gate node. A charging path including a charging resistor is situated between the input node and the first gate node. A discharging path including a discharging resistor is situated between the input node and the first gate node. A gate path is situated between the input node and the first gate node. A power switch transistor, whose gate is connected to the first gate node, is provided. A gate path includes a gate resistor. The driver circuit is configured so that, during a switching process of the power switch, the gate path is temporarily short-circuited either via the charging path or the discharging path, to increase the slope of the switching behavior of the power switch.
