CURRENT SENSING BI-DIRECTIONAL SWITCH AND PLASMA DISPLAY DRIVER CIRCUIT

摘要

A discharge sustain driver circuit for a plasma display device, the driver circuit comprising a first transistor switching circuit for switching a DC bus voltage across the plasma display device; a storage capacitance; at least one inductor; and first and second bi-directional switching circuits coupled in series and being coupled to the first switching circuit to transfer charge from the plasma display device through the at least one inductor to the storage capacitance, and back to the plasma display device; and a controller for the bi-directional switching circuits to control the bi-directional switching circuits so as to receive the charge on the storage capacitance and return the charge in an opposite charge direction to the plasma display device.
