摘要： A drive circuit with a circuit for transmitting a signal from a primary side having a first ground to a secondary side having a second ground. The transformer has capacitive coupling between the primary and secondary sides. The transformer has an ON transmission branch and an OFF transmission branch, which each have a first partial branch and a second partial branch. Capacitive coupling between the primary and secondary sides is effected in each partial branch by high-voltage capacitors. In the inventive method, in each transmission branch, the signal generates a current flow through a first HV capacitor of a first partial branch and an inverse current flow through a second HV capacitor of a second partial branch. This respective current flow is detected on the secondary side and is supplied to an evaluation circuit common to the two partial branches and reconstructs the primary-side input signal on the secondary side.

摘要： A TOP level switch for use in a drive circuit in power-electronic systems having a half-bridge circuit formed by two power switches, a first so-called TOP switch and a second so-called BOT switch, which are arranged connected in series. The TOP level shifter transmits an input signal from drive logic to a TOP driver. In this case, the TOP level shifter is designed as an arrangement of an UP and a DOWN level shifter path, as well as a downstream signal evaluation circuit. In the associated method for transmission of this input signal, the signal evaluation circuit passes an output signal to the TOP driver when either the UP or the DOWN, or both, level shifter paths emit a signal to the respectively associated input of the signal evaluation circuit.

摘要： 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.
