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.
