A multi-mesh loop matrix model for a piezoelectric transformer operating with switched circuit excitation is presented. The modeling requires the inclusion of harmonics and the coupling of vibration in different directions of the piezoelectric transformer. Simulation and experimental results are used to validate the proposed model using matrix circuits. The proposed method has also compared with other conventional modeling method, a good agreement is obtained.
