Being compared with conventional fluorescent lamps, the cold cathode fluorescent lamps (CCFL) have more compact size, longer lifetime and higher light efficiency. Therefore, they have been widely used as illuminating source and background lighting in LCD panel and notebook computers. However, there is lack of a suitable CCFL model which can be used for ballast designer to apply in their designing...
A lumped equivalent circuit model for the radial mode piezoelectric transformer is presented, based on a one-dimensional analysis of the radial vibration mode and the constitutive piezoelectric equations. The model allows each of the components in the piezoelectric transformer equivalent circuit to be calculated from the appropriate material properties and device dimensions, thereby facilitating the...
Average model of three-phase PWM converters is important in both theory and practical engineering. To remedy defects possessed by the existing average models of three-phase boost rectifiers and voltage source inverters (VSI), this paper proposes and derives another new-formed models that are easy-to-use and more suitable for computer simulation. During establishing switching models, the number of...
