28KHZ or 40KHZ 2500W Ultrasonic Cleaning Generator PCB For Submersible Ultrasonic Transducer Pack

Resonant circuit board of ultrasonic transducer An impedance and resonant frequency separately excited drive circuit, including DC power supply, switch components, voltage divider capacitor assembly, transformer, resonant inductance, etc., can effectively ensure that the ultrasonic cleaning transducer cannot be damaged due to the voltage, the maximum output voltage is controllable, and the output voltage changes little with the operating frequency.

The wide frequency range of the resonant circuit board of the ultrasonic transducer reduces the complexity and cost of the circuit board, and improves the safety of the circuit board. An electromagnetic ultrasonic transducer for resonant control and its control method, comprising a high-frequency power oscillation signal output circuit, a coil with a bias magnetic field, an echo signal detection circuit, and a main controller; The high-frequency power oscillation signal output circuit consists of a high-frequency inverter drive circuit, an impedance matching network, and a static matching capacitor. The echo signal detection circuit includes a high-voltage isolation circuit and an echo signal filtering circuit.

The main controller of the resonant circuit circuit board of the ultrasonic transducer is used to collect the filtered ultrasonic echo signal, and adjust the high-frequency inverter drive frequency according to the envelope amplitude feedback of the ultrasonic echo signal. The control method of the improved resonant control electromagnetic ultrasonic transducer can provide the power pulse voltage required by the electromagnetic ultrasonic transducer, and the static matching capacitor and coil work in a quasi resonant state, Thus, the maximum power ultrasonic signal can be excited in the tested object with low harmonic content, resulting in high detection accuracy of the improved resonant controlled electromagnetic ultrasonic transducer
