Abstract

An electronic switch with a switching element of the type of a semiconductor switch with the mode of operation of at least one FET, so that due to the technology it also has an internal body diode in inverse operation. A control circuit for executing the operating commands is set up so that gate in inverse operation receives such a voltage that the body diode is still currentless. In addition, a functional unit of the control circuit is set up to cause the switching element to assume the ON conducting state as a function of a commutation voltage or a commutation current, i.e., in inverse operation.
