Abstract
A power supply which inputs a first direct-current voltage from the outside and outputs a high direct-current voltage to a plasma display panel. The power supply connects the input direct-current voltage to a positive polarity side of a first capacitor of a plurality of N capacitors connected in series to each other and connects a negative polarity side of the first capacitor to a ground (step 1); connects the input direct-current voltage to a positive polarity side of an Mth capacitor of the N capacitors and connects a negative polarity side of the Mth capacitor to the ground (step 2); repeats step 2 for M=2 to N (step 3); and outputs a voltage of the positive polarity side of the first capacitor to the plasma display panel (step 4).
