Abstract

A new multi-output LLC resonant converter is proposed for high efficiency and low cost plasma display panel (PDP) power module. In the proposed converter, zero-voltage (ZV) turn-on of the primary MOSFETs and zero-voltage (ZC) turn-on and turn-off of the secondary diodes are guaranteed in the overall input voltage and output load ranges. In addition, the primary MOSFETs and the secondary diodes have the low voltage stresses clamped to input and the output voltages, respectively. Therefore, the proposed converter shows the high efficiency due to the minimized switching and conduction losses. Moreover, by employing the transformer with multiple secondary windings, the proposed converter can have multiple outputs, which show the great crossregulation characteristics. Therefore, the proposed converter is suitable for high efficiency and low cost PDP power module.
