120W Ultrasonic Transducer Driver Generator Board Ultrasonic Sensor Pcb Ultrasonic Generator Pcb

In order to solve the problem that the traditional ultrasonic generator can only track manually and can not achieve automatic frequency tracking, the circuit board of the low-power ultrasonic generator includes a rectifier filter circuit, an inverter unit, a matching circuit, a transducer, and an oscillation and drive circuit. The control unit also includes a current detection circuit which detects the current input to the rectifier filter circuit and outputs a current detection signal to the control unit
