Paper Title:
Dome-Shaped High Power Transformer for Driving A 61 W T5 Lamp
  Abstract

Processing and properties of a dome-shaped piezoelectric transformer with a composition of 0.03Pb(Sb0.5Nb0.5)O3-0.03Pb(Mn1/3Nb2/3)O3-0.465PbTiO3-0.475PbZrO3 have been investigated. A dome-shaped sample was fabricated by powder injection molding. The dimension of the domeshaped sample was a 28 mm in diameter and 2.1mm in thickness with a curvature radius of 18 mm. Finite element modeling for the complicated piezoelectric transformer was applied to simulate strains and vibration mode in the sample. The high power characteristics of a dome-shaped piezoelectric transformer were examined by the lighting test for 27 and 34 watt T5 circle lamps connected in series. The series connected T5 circle lamps were successfully driven by the domeshaped piezoelectric transformer with sustaining efficiency higher than 98.5%. The transformer with ring(input)/dot(output) electrode ratio of 2.5 exhibited the maximum properties in terms of output power, efficiency and temperature stability.
