The driving circuit board of micro ultrasonic generator is different from the traditional constant current method of “frequency tracking first and then adjusting the exciting voltage”. In the process of frequency tracking, the exciting voltage is adjusted at the same time, and the adjustment speed of the rising exciting voltage is much less than that of frequency tracking, while the adjustment speed of the decreasing exciting voltage is much greater than that of frequency tracking, Thus, the over current in the adjustment process when the load of the transducer changes can be avoided or reduced. That is, the over current suppression in the process of transducer steady speed control is realized through the asymmetry of transducer exciting voltage regulation speed.
