SWITCHING MODE POWER SUPPLY CIRCUIT FOR PLASMA DISPLAY PANEL

摘要

PURPOSE: A switching mode power supply circuit for a plasma display panel is provided to reduce manufacture costs by simplifying the configuration of a circuit. CONSTITUTION: A switching mode power supply circuit for a plasma display panel is includes an input unit(100), a PFC part, and an output unit. The output unit comprises a first transformer former(200), a 13V voltage output part(220'), a D5V voltage output part(230), a stand by voltage output part(240), a second transformer(300), a sustain voltage output part(320), an address voltage output part(330), and a gate voltage output part(210'). The primary side of the first transformer former is connected to the output terminal of the PFC part. The 13V voltage output part is connected to a primary winding of the secondary side of a first transformer. The D5V voltage output part is connected to the secondary winding of secondary side of the first transformer. The stand by voltage output part outputs the stand by voltage of 5V. The second transformer is connected to the primary side of the first transformer. A sustain voltage output part outputs the sustain voltage. The address voltage output part outputs an address voltage. The gate voltage output part outputs a gate voltage of 15V.
