High quality ultrasonic analog power supply ultrasonic N95 mask welding machine welding generator

Description:

Ultrasonic power supply is divided into self-excitation mode power supply and other excitation mode power supply according to the design.

　　 The self-excited circuit has no signal source. It integrates the oscillation, power amplifier, output transformer and transducer to form a closed loop. The loop meets the amplitude and phase feedback conditions to form an oscillator with power amplification. And it resonates at the mechanical resonance frequency of the transducer. Generally used in small devices with a small number of ultrasonic transducers; but for a large number of ultrasonic transducers, it cannot be debugged to achieve the resonance effect. Therefore, the ultrasonic power supply of industrial ultrasonic cleaning equipment mostly adopts other excitation methods.

　　 The structure of the externally excited power supply mainly includes two parts, the front stage is the oscillator, and the rear stage is the amplifier. Usually through the output transformer coupling, the ultrasonic energy is added to the transducer. The circuit of the external excitation mode consists of two parts, the signal source part and the signal amplification part.

The signal source part uses the signal generation and control part with CPU as the core, which is generally driven by 12-15V voltage to generate a square wave signal to be supplied to the signal amplifier circuit; the timing control, adjustment and other additional functions of the ultrasonic power supply can be controlled by the signal source signal The output mode is completed and low voltage control is adopted, and the safety and reliability will be definitely high.

　　The signal amplifying part is to amplify the signal generated by the signal source and output it to the ultrasonic transducer. The difference of the output circuit and voltage of the ultrasonic power supply of different circuits is an important reason for the high or low transmission efficiency. The output voltage is low, the generator consumes a large amount of electric energy, and the vibrator is also easy to generate heat, and the induced electric field generated is strong. Properly adjusting the circuit and increasing the voltage output to the ultrasonic transducer may achieve good results.
