Abstract

The invention discloses a touch controlled multi-frequency ultrasonic power supply. The ultrasonic power supply comprises an input circuit, a rectifying filter circuit, a chopper circuit, an inverter circuit, a matching circuit, a sampling circuit and a single chip microcomputer, wherein the single chip microcomputer is respectively in electric connection with the input circuit, the rectifying filter circuit, the chopper circuit, the inverter circuit and the matching circuit and is used for receiving and sending an electric signal for controlling the circuits; the input circuit, the rectifying filter circuit, the chopper circuit, the inverter circuit and the matching circuit are successively serially connected with each other; the output end of the matching circuit is connected with the sampling circuit and an energy converter; the sampling circuit is used for feeding back the sampling signal to the single chip microcomputer. According to the touch controlled multi-frequency ultrasonic power supply, the single chip microcomputer is used for controlling the other circuits and the corresponding circuit can process and then output the electric signal according to the electric signal received or outputted by the single chip microcomputer, so that the energy converters in different frequency bands can be matched and the accurate judgment for resonance point can be realized.

Description

technical field [0001] The invention relates to the field of mechanical equipment and belongs to the aspect of power supply equipment, in particular to a touch-controlled multi-frequency ultrasonic power supply and a control method thereof. Background technique [0002] The current ultrasonic power supply technology mainly includes self-excited generators and other excited generators. The self-excited generator uses the capacitance of the transducer itself and the matching circuit to form a resonant circuit. Each transducer needs to manually adjust the parameters of the matching circuit to work normally, and the operating frequency range is narrow; with the operation of the circuit, the device's The thermal effect is constantly changing, which will lead to extremely unstable frequency and energy; the control of energy requires a special control module, and it cannot be connected to the host computer. [0003] Separately excited ultrasonic power supplies can be divided into ...

Problems solved by technology

[0004] The current common ultrasonic power supplies mentioned above, because the operating frequency of the circuit is adjusted by adjusting the parameters of components such as resistors and capacitors, the operating frequency range generally does not exceed 1KHz, and it is impossible to drive a variety of frequency transducers, such as To use transducers with multiple frequencies, professionals from the power supply manufacturer need to re-adjust the power supply hardware parameters. Generally, end users cannot achieve simple and fast adjustments. Once the power supply parameters are adjusted, the original matching transducer It cannot be used, which directly causes many users to choose to re-purchase a power supply, which greatly increases the cost of ultrasonic equipment and limits the use and promotion of ultrasonic power supplies.
