^{Isolated Drived Ultrasonic Cleaner Generator , Sonic Frequency Generator Electromagnetic}

^{1. Brief description of each component related function:}

^{A, rectifier bridge: converts AC voltage into DC voltage;}

^{B, common mode inductance: filter high frequency electromagnetic clutter generated by circuit operation to prevent it from polluting external power supply.}

^{C, current detector: precision current detector, the input current signal is converted into a high-precision voltage signal, which is shaped and supplied to the main control circuit to achieve stable power.}

^{D, Transistor: A phase-shifted full-bridge architecture consisting of four high-power IGBT transistors converts the DC voltage signal into a high-frequency AC voltage signal.}

^{E, drive circuit: isolated drive.}

^{F, auxiliary transformer: converts the mains into low-voltage alternating current, and after rectification and filtering, it is supplied to the signal processing part and the display board part.}

^{G, frequency fine-tuning: adjusting the potentiometer can adjust the frequency parameter of the generator to a certain extent;}

^{H, current trim: Adjust this potentiometer to adjust the input current to a certain extent, thus changing the output power.}

^{I, current selection switch: It can be adjusted by 6 gears from 1 to 6. Note that 1-5 is the current reference. The smaller the number, the larger the current reference. 6 is a current multiplier switch. For example, when the current is 2, the current is 2A, and when 5 and 6 are simultaneously turned on, the output is 4A.}

^{J, Inductors 1 and 2 can match different inductances, wherein the inductance corresponding to inductor 1 is R11, R12, R13, R14, R15; the inductance corresponding to inductor 2 is R1, R2, R3, R4, R5; The larger the number, the larger the inductance. The sum of the inductances of the two is the total inductance. When debugging, the inductor must be based on the principle of taking priority.}

^{K, transformer turns ratio selection: RA and RB, RA is less than RB, in general, RA is suitable for yellow ceramic transducers, RB is suitable for black ceramic transducers.}
