Abstract
A control apparatus for driving a semiconductor switch of an inverter. A drive circuit generates a driver signal on the basis of a switching signal generated by a control regulation system of the inverter. A driver circuit which is coupled between the drive circuit and a control input of the semiconductor switch is configured to receive the driver signal and to generate, on the basis of the driver signal, a control signal which drives the semiconductor switch. The control signal is fed into the control input of the semiconductor switch. A regulation circuit is coupled to the drive circuit and is configured to detect a voltage signal dependent on the voltage across the semiconductor switch, to generate a regulation signal which is dependent on the voltage signal and is intended to regulate the driver signal, and to feed the regulation signal into the drive circuit.
