The invention disclose a phase-shift-circuit-based ultrasonic processing driver comprising a commercial power input module, a rectifier and filter circuit, a full-bridge inverter module, a transformer, a matching network module, an electromagnetic conversion module, a transducer load module, a driver module, an over-voltage and over-current protection circuit, a display screen module, a signal detection module and an MCU module. According to the invention, the structure is designed ingeniously and reasonably. On the basis of a phase-shift control strategy, linear adjustability of the output power of the inverter circuit is realized, a square wave outputted by the inverter bridge is changed into a same-frequency sine-wave signal; and then a sine-wave signal with adjustable power and frequency is obtained finally. Moreover, the power is high, the frequency tracking is realized accurately, and the linear output power becomes precise. Besides, because of the single-chip-microcomputer-based control, digital control of the system can be realized easily; and advantages of sweep frequency realization, linear power control, real-time signal detection, and work log recording are realized. In addition, the drive having characteristics of simple structure, easy realization, and simple operation can be popularized and applied widely.
Description
technical field [0001] The invention belongs to the technical field of ultrasonic machining drivers, and in particular relates to an ultrasonic machining driver based on a phase-shifting circuit. Background technique [0002] The ultrasonic driver can also be called an ultrasonic drive power supply, a device that provides the same frequency sine wave signal required by the ultrasonic transducer. As an interdisciplinary subject, it is accompanied by the development of multidisciplinary technologies such as automatic control, power electronics technology and signal detection. According to the principle of the driver, the ultrasonic driver can be divided into two types, which are composed of a signal amplifier circuit and are suitable for low power, and those composed of a switching power supply and are suitable for high-power use. Common electronic (transistor) transistor drivers and analog integrated IC circuit drivers on the market are signal amplification types, and driver...
