Abstract: A technique describing voltage transformation of a transiently oscillating Piezoelectric Transformer (PT) has been reported. The first part is dealing with determination of input and output voltage of PT at resonance using Pico scope; a computer based oscilloscope. It was found that, as time goes, the output voltage of the PT fluctuated due to frequency aging; therefore a second part of experimental set-up was needed to record transformation ratio as a function of transient time. To do that, Computer 2 was connected to DMM1 and DMM2, for the purpose of measuring the voltage transformation, in additional to that, Lab view program was installed in Computer 2 and used to calculate voltage ratio as a function of transient time. In this technique, caution was taken when interpreting results from resonance (110.50 kHz) relative to PT operating in frequency (kHz) range between (109 Í 110.50 Í 114) as a function of transient time.
