Maximum efficiency control of a system composed of a piezoelectric transformer and cold cathode tube driven by inverter, and its characteristics

This paper concerns a control method in which cold cathode tube used for liquid crystal display, etc. is made to light at maximum efficiency. In the system composed of inverter, LC circuit, piezoelectric transformer, and cold cathode tube, tube current is controlled at the height of inverter output...
