超声波发生器原理介绍:
The principle of ultrasonic generator is introduced
超声波发生器,又称超声波驱动电源、电子箱、超声波控制器,是大功率超声系统的重要组成部分。超声波发生器作用是把市电转换成与超声波换能器相匹配的高频交流电信号,驱动超声波换能器工作。大功率超声波电源从转换效率方面考虑一般采用开关电源的电路形式。超声波电源分为自激式和它激式电源,自激式电源称为超声波模拟电源,它激式电源称为超声波发生器。
Ultrasonic generator, also known as ultrasonic driving power supply, electronic box and ultrasonic controller, is an important part of high-power ultrasonic system. The function of ultrasonic generator is to convert the municipal power into high frequency AC signal matched with ultrasonic transducer, and drive the ultrasonic transducer to work. Considering the conversion efficiency of high-power ultrasonic power supply, the circuit form of switching power supply is generally adopted. Ultrasonic power supply is divided into self excitation power supply and other excitation power supply. Self excitation power supply is called ultrasonic simulation power supply, and other excitation power supply is called ultrasonic generator.
较自激式震荡电路结构在输出功率增加10%以上。超声波放大电路形式采用线性放大电路和开关电源电路。
The ultrasonic generator adopts the world's leading other excitation oscillation circuit structure, and its output power is increased by more than 10% compared with the self-excited oscillation circuit structure. Linear amplifier circuit and switching power supply circuit are used in ultrasonic amplification circuit.
开关电源电路的优点:转换效率高,因此大功率超声波电源采用此形式。
Advantages of switching power supply circuit: high conversion efficiency, so high-power ultrasonic power supply adopts this form.
线性电源电路的优点:不严格要求电路匹配,允许工作频率连续快速变化。
Advantages of linear power supply circuit: it does not strictly require circuit matching and allows continuous and rapid change of working frequency.
