Abstract
An energy recovery circuit for a plasma display panel having a reduced number of components. The energy recovery circuit includes a source capacitor, an inductor, a panel capacitor and six switches. The circuit is designed so that the source capacitor, the inductor and two of the switches are shared in operation, thereby reducing the number of components.
Claims8
An energy recovery circuit, comprising:
- a panel capacitor equivalently arranged within a discharge cell, the panel capacitor including a scan electrode and a sustain electrode;
- a source capacitor;
- a first switch, a second switch, a third switch, a fourth switch, a fifth switch and a sixth switch;
- an inductor;
