| Abstract: | A driving circuit for USM is very complex,it needs a frequency automatic follow-up circuit to follow up the resonant point.To simplize the circuit,a self-oscillating ciruit is to be constructed.its frequency is adjustable to the resonant frequency.Here it is successfully used to drive and control USM.In this paper,we expatiate the principal of self-oscillating circuit and point out which type of USM allows to use a self-oscillating circuit. |
