| Abstract: | This article constructs a type of frequency-modulated ultrasonic generator and analyses its high-speed phase locking mechanism. Through the feedback of transducer’s electricity, the phase locking speed of ultrasonic generator using embedded digital true RMS heuristic approach algorithm is able to increase dozens of times compared with the traditional ones,which reaches the high-speed phase locking demand and meets the challenge of high-speed resonance requirement when transducer system is working. |

| Keywords: | high speed phase locking true root-mean-square(RMS) square root ultrasonic bond |
