| Abstract: | According to the principle of compensating a leg of circuit by a hybrid bridge circuit , a method for automatically controlling of the frequency and amplitude in a power ultrasonic equipment is proposed , in which the technologies of phase-locked loop (PLL) and analog multiplier are used. It is shown that the controlling method has a wider range of frequency tracking and it makes the equipment a wider range of load fluctuation and a steady working condition . |
