A New High Efficiency Active Clamp Forward Converter Suitable for the Sustaining Power Module of A Plasma Display Panel

Abstract

A new high efficiency active clamp forward converter suitable for the sustaining power module (SPM) of a plasma display panel (PDP) is proposed. It has a wide zero voltage switching (ZVS) range without inserting additional resonant inductor. Also, it features simpler structure, lower cost, less mass, and no effective duty loss. Furthermore, voltages across all rectifier diodes are clamped on the output voltage, which results in a higher efficiency.
