CIRCUIT AND METHOD FOR GENERATING CONTROL SIGNALS FOR COMPONENTS ON A HIGH REFERENCE POTENTIAL

摘要

In a circuit (1) for producing or transmitting control signals (Q) for a current inverter (2) comprising at least one first switch (Shigh) with a high potential and a second switch (Slow) with a low potential, a connection point between the two switches (Shigh, Slow) forms the output of the current inverter (2). The circuit (1) also comprises a capacitor (Ccap) which a) is connected to the output of the current inverter (2) in a first operating phase by means of switching elements (S1-S4), in such a way that it enables a current flow in a state wherein the two switches (Shigh/ Slow) of the current inverter (2) are open, and b) is connected to the current inverter output in a second operating phase by means of the switching elements (S1-S4) with high impedance, such that a control signal (Q) applied to a side of the capacitor (Ccap) by a control device is transformed into a higher potential.
