| 摘 要： | 针对超声清洗过程中超声换能器谐振频率发生漂移的问题,设计了一种由D触发器、单片机、数字电位器和压控振荡器组成的频率跟踪系统。该系统利用单片机检测超声清洗电源负载的电压、电流的相位差,并通过数字电位器来改变压控振荡器的输出频率。与其它频率跟踪方法相比,该系统降低了程序编写的复杂性,电路简单且易于实现。 |

| Abstract: | During the process of ultrasonic cleaning,the resonant frequency of ultrasonic transducer may drift.Aimed at this problem,a frequency tracking system is designed in this paper,which mainly consists of D Flip-flops,single-chip microcomputer,digital potentiometer and voltage-controlled oscillator(VCO).In this system,the output frequency of VCO is changed by a digital potentiometer which is controlled by a single-chip microcomputer measuring the phase difference between voltage and current.Compared with other ... |
| Keywords: | ultrasonic cleaning frequency tracking digital potentiometer voltage-controlled oscillator(VCO) |
