A drive circuit in power electronic systems comprising a half-bridge circuit of two power switches, a first so-called TOP switch and a second so-called BOT switch, which are arranged in a series circuit. The drive circuit has a BOT level shifter for transmitting an input signal from a drive logic to a BOT driver. The BOT level shifter is formed as an arrangement of an UP and a DOWN level shifter branch and a signal evaluation circuit connected downstream thereof. In the inventive method for transmitting the input signal, the signal evaluation circuit transfers an output signal to the BOT driver at least one of the UP and DOWN level shifter branches outputs a signal to the respectively assigned input of the signal evaluation circuit.
