摘要:
A plasma display and a driving device therefor. In a sustain discharge driving circuit that includes a power recovery circuit and a sustain voltage supply circuit, a transformer is used. The transformer includes a primary coil and a secondary coil that are coupled with each other. The primary coil of the transformer is connected in parallel to a panel capacitor serving as a capacitive load so as to increase a change of a voltage that is applied to an inductor, such that a voltage rising period and a voltage falling period are reduced. With the reduction of the turn-on time of a switch, the power consumption of the switch is reduced. Further, as the inductor initially stores current, the occurrence of hard switching is reduced when a sustain discharge voltage is applied and elements of the circuit are protected.

Disclosed herein are a multilayer ceramic capacitor, a dielectric composition capable of sintering at a lower temperature and having a small variation in dielectric constant, a multilayer ceramic capacitor using the same, and a method thereof. The dielectric composition includes BaTiO3, MgCO3, Y2O3, Cr2O3, Mn2V2O7, and xBaO-yZrO2-zSiO2 acting as a sintering agent (where 0.1≦x≦0.3, 0.1≦y≦0.3 and 0.4≦z≦0.8, x+y+z=1), wherein when representing the composition with the formula aBaTiO3-bMgCO3-cY2O3-dCr2O3-e(Mn2V2O7)-f(xBaO-yZrO2-zSiO2), the ratio of the components satisfies the conditions of a=100, 0.1≦b≦3.0, 0.3≦c≦2.0, 0.05≦d≦0.2, 0.01≦e≦1.5, 0.5≦f≦3.0 based on the molar ratio. When manufacturing a multilayer ceramic capacitor of a higher capacitance, which is formed to have the thin layer structure of 4 μm or less, short circuits between internal electrodes and the deterioration in capacitance due to massing of the electrodes into ball at the ends may be remarkably reduced.
