| Popis: | 92 In this thesis, a backlighting source implemented by piezoelectric transformer as an energy inverter is proposed. The piezoelectric transformer is driven by a half-bridge series-resonant parallel-loaded inverter. Modeling piezoelectric transformer and cold-cathode fluorescent lamp for system analysis is conducted. A prototype of a half-bridge series-resonant inverter with piezoelectric transformer for driving a 1.6W and 2.8W cold-cathode fluorescent lamps is realized and examined. A dimming process is employed by frequency-modulation. The experimental result is close to the theoretical predictions. |
