Abstract
A circuit arrangement for controlling a transistor with an insulated gate, a gate driver for generating a driver signal, and a capacitor parallel to the gate-source path of the transistor, wherein the gate driver is designed for generating a driver signal greater than or equal to zero volts, an inductor is provided for forming a resonant circuit with the capacitor, and a switching element is provided in the resonant circuit, which is designed for interrupting the resonant circuit after recharging the capacitor. The part of the circuit arrangement downstream of the gate driver is designed for exclusive voltage supply using the driver signal of the gate driver, and the switching element is formed by an additional transistor, a first freewheeling diode is arranged parallel to the switching element, and the inductor of the resonant circuit is arranged between the additional transistor and the gate of the transistor.
