When the full bridge phase-shifting circuit inverts and amplifies the energy passing through it and transfers it out through transformer T1, voltage V and current C are generated on the output circuit of the full bridge phase-shifting circuit. The voltage transformer CT1 and current transformer CT2 in the sampling circuit will induce voltage signals of the same proportion, which will be adjusted by U1A and U1B operational amplifiers and sent to the phase detection circuit and current effective value circuit respectively, The logic chips U2A, U2B, and D trigger chips U3A and U3B in the phase detection circuit separate the leading and lagging amounts of the phase between the current signal and the voltage signal, and send them to the operational amplifier U3. U3 converts the phase difference into a voltage signal and sends it to the DSP main control chip for processing. U4 in the current effective value circuit 7 converts the adjusted current signal into a voltage value corresponding to the current RMS value, and sends it to the DSP main control chip 8 for processing.
A separate excitation type automatic frequency tracking ultrasonic generator circuit includes an automatic frequency tracking control circuit and an ultrasonic signal main signal circuit. The automatic frequency tracking circuit includes a voltage divider circuit, CT1 high-frequency pulse transformer, CT2 high-frequency pulse transformer, peripheral discrete components, parallel resonance circuit, multiplier chip, operational amplifier chip, second operational amplifier chip, voltage comparator, multi frequency oscillator, and digital to analog conversion chip; This utility model adopts an automatic frequency tracking circuit to track the working frequency of the machine equipment, avoiding the trouble of readjusting the working frequency of the machine every time the ultrasonic mold is replaced. The pulse width modulation chip automatically compensates for power and amplitude, which not only has high accuracy, high power, high energy conversion efficiency, convenient use, but also low failure rate, significantly reduced maintenance costs, and longer service life
