Abstract：To solve the problems of low efficiency and poor stability of traditional drive power，a novel drive power of low frequency ultrasonic nozzle was developed. The novel drive power was designed with singleended flyback topology circuit. An intelligent drive program of ultrasonic atomization nozzle was developed by embedded visual C++（EVC） program language on Wince5.0 platform and ARM9.0. In the program, frequency and duty of PWM could be adjusted intelligently to ensure the nozzle working near the resonant frequency. Impedance analyzer PV70A was applied to measure equivalent circuit parameters of the nozzle to compute the matching inductance by corresponding mathematical formula. The simulation model of the novel drive power was established by Multisim10.0 .The transformer was featured by ideal transformer model and distribution parameters of leakage inductance and turntoturn capacitance. The optimum parameters of the drive power were obtained by simulation，and the simulation result was verified by actual circuit.
