发明名称 Method of controlling a circuit arrangement for the ac power supply of a plasma display panel
摘要 A method of controlling a circuit arrangement for an AC voltage supply of a plasma display panel, the circuit arrangement comprising at least a transistor bridge constituted by the bridge transistors (T 1 , T 2 , T 3 , T 4 ), an input voltage (U 0 ), a capacitor (Cp) of the plasma cell and a charging circuit comprising an auxiliary voltage (Uh), a first auxiliary transistor (T 11 ) and a first coil (L 1 ) and at the beginning of the charging operation the first auxiliary transistor (T 11 ) is turned on, characterized in that once the first auxiliary transistor (T 11 ) has been turned on, the second bridge transistor (T 2 ) of the half bridge continues to be turned on for a delay time tv and is turned off after the delay time tv has elapsed.
