Patent ID: 7425949

Claim:
A high voltage LCD power supply system, comprising: a first inverter controller coupled to a first power train for converting a DC signal to a first AC signal; a second inverter controller coupled to a second power train for converting said DC signal to a second AC signal wherein said second AC signal is about 180 degrees out of phase relative to said first AC signal; a first transformer having a primary side and a secondary side, said primary side of said first transformer directly connected to said first power train and configured to receive said first AC signal, said secondary side of said first transformer having a first terminal and a second terminal, wherein a first feedback circuit is directly connected to said second terminal of said secondary side of said first transformer and said first inverter controller; a second transformer having a primary side and a secondary side, said primary side of said second transformer directly connected to said second power train and configured to receive said second AC signal, said secondary side of said second transformer having a first terminal and a second terminal, wherein a second feedback circuit is directly connected to said second terminal of said secondary side of said second transformer and said second inverter controller; and a cold cathode fluorescent lamp directly connected to said first terminal of said secondary side of said first transformer and said first terminal of said secondary side of said second transformer.
