As the sensing part (400) is formed to provide data about the DC current sensed by the broadband amplification part (200) to the control part (100), the sensing part (100) can be operated by searching for the most efficient resonant frequency in the vicinity of inputted frequency data within an inputted broad frequency band. Therefore, the multi-frequency ultrasonic generator is capable of enabling more efficient cleaning work as well as generating stronger output through various resonant frequencies.
