ABSTRACT:
A driving circuit for reducing noise of a ceramic capacitor, that is capable of driving a plasma display unit, is provided. The circuit includes a circuit board, a first switch, a second switch, a first capacitor set, a second capacitor set, and a control switch. The first switch is located on the circuit board and coupled to the second switch at a connecting point and the connecting point is connecting to the plasma display. The first capacitor set is coupled to the first switch and provides a first driving voltage to turn on the first switch. The second capacitor set is coupled to the second switch and provides a second driving voltage to turn on the second switch. The control switch can control the first switch and the second switch to carry out a charged and discharged operation. Moreover, the first and second capacitor sets both include an even number of ceramic capacitors subsequently those are located in reverse.
