A HYBRID SIMULATION METHOD FOR ACTUATION OF PIEZOELECTRIC TRANSFORMER COMBINING CIRCUIT AND FINITE ELEMENT ANALYSIS
For simulation analysis of piezoelectric device with a driver circuit,this paper proposes a hybrid simulation scheme with a combination of multi-physics field finite element simulation and circuit analysis software.Taking the drive analysis of piezoelectric transformer as an example,the paper firstly uses the circuit analysis software Multisim to carry out the actuation simulation with the equivalent circuit model.Then,the modal analysis of the piezoelectric transformer is carried out in Comsol,and the driving circuit is imported by the SPICE netlist for hybrid simulation.Finally,the paper introduces the temperature model of the piezoelectric parameter d33 and analyzes the effect of temperature changes on the driving performance of the piezoelectric transformer.Comparing the simulation data,the results of the hybrid simulation are more accurate and more in line with the actual working process of the piezoelectric transformer.
