  • Power supply system for liquid crystal monitors
    Patent number: 7233113
    Abstract: A power supply system for liquid crystal monitors includes a first DC/AC converter (FBS, HBS) operating at predetermined frequency and duty-cycles and being fed by a second DC/DC converter (FC) which regulates the circuit voltage. The feeding system can feed all the fluorescent lamps (L, L1, LN) in the monitor through a bus connection which transmits the output sinusoidal voltage (SG1, SG2, SG3) from the first DC/AC converter (FBS, HBS) to the primary windings of a plurality of parallel connected piezoelectric transformers (PT, PT1, PT2, PTN, PT2N) which are connected with the fluorescent lamps (L, L1, LN).
