In the thesis, PT equivalent circuit and characteristics is introduced, also CCFL’s voltage to current characteristics will be found experimentally in order to derive the first order steady state equivalent circuit, also the use of PT characteristics to control the current through CCFL is mentioned. By using the PT’s and CCFL’s equivalent circuit with fixed voltage and current, the best capacitance and introduce can be derived, so that the current follow into CCFL is not too large or too small. Last of all from the design step by using fixed frequency control method the CCFL’s driving circuit using PT can be realized, and by using the pulse width modulation, to control PT input voltage such that CCFL’s brightness is controlled.
