Abstract
In a ballast circuit, the piezoelectric transformer (PT)
is used to replace the conventional inductor-capacitor resonant
tank saving valuable space and cost. 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.
