Voltage Gain and Efficiency Ana1ysis of Piezoelectric Transformer using Lumped Constant Equivalent Circuit

Rosen형 압전 트랜스포머의 집중등가회로를 사용한 승압비 및 효율 해석

In this paper, The load characteristics on the voltage gain and efficiency were analyzed sing an lumped constant equivalent circuit of the piezoelectric transformer. These analytical results are confirmed by experiments. Theoretical values of voltage gain were nearly constant with experimental ones. However, It was shown that theoretical values of efficiency had higher values than experimental ones.
