| Abstract: | Based on the conventional lumped parameter circuit model,piezoelectric transformer electric expression can be deduced from admittance matrix Y parameters of two-port network,and the characteristics of disk-type step-down piezoelectric and inverse connected Rosen type transformers are simulated and analysed.The results indicate that the electric characteristics of the inverse connected Rosen type is basically consistant with that of some other step-down piezoelectric transformers when the load is matched. |
