During circuit operation, a very high voltage is required to initially ignite the lamp while during sustained operation the voltage requirements are significantly reduced. With ballast in mind, a design process has been developed to optimize a radial mode piezoelectric transformer or Transoner® to fit a specific application while simultaneously providing highly efficient performance and the capability to provide ZVS to the switches. The design procedure was verified by a custom-designed PT operating in a 32-W ballast.application/pdf1386066 bytesapplication/pdfzh-TWBallast circuitinductor-capacitor resonant tankpiezoelectric transformer (PT)Transonerjournal articlehttp://ntur.lib.ntu.edu.tw/bitstream/246246/200611150121663/1/2613.pdf
