<p>In the case of a plasma screen, a circuit is provided which altenatly applies to the total capacitance of the screen or panel a positive and a negative voltage for a reset process. An inductance is located in the current path, in order to ensure recovery of the energy in the total capacitance. In the case of such a circuit, the object is to improve the drive to and the process of erasing a pixel. The AC voltage generator according to the invention is distinguished by the fact that a diode (D) is arranged in parallel with a first switch (T3), which is connected to a first operating voltage (E+), so that a greater gradient can be achieved for the voltage profile of the voltage (Vp). In particular a control circuit for a plasma screen for a television set.</p> |
