The 28KHZ/40KHZ 400W ultrasonic circuit board completes two functions: power amplification and load matching, that is, power amplification amplifies the control signal; Load matching is achieved by using transformers and inductors connected to the input end of the transducer, which can improve the energy transmission efficiency between the driving circuit and the transducer, enabling the transducer to obtain sufficient power. At the same time, the matching circuit can also be used for filtering, converting square waves into sine waves, and reducing high-frequency harmonics. The external transformer further boosts the voltage, enabling the ultrasonic motor to operate normally.
The 28KHZ/40KHZ 400W ultrasonic circuit board cannot meet all filtering requirements due to the fact that the sine wave output by the driving circuit is obtained through matching circuit filtering, and different ultrasonic motors have a large operating frequency range. Therefore, the universality of using switch inverter drive circuits is relatively low.
28KHZ/40KHZ 400W ultrasonic circuit board is a frequency synthesis technology that directly synthesizes the required waveform based on the phase concept, which can easily generate sine signals with adjustable frequency, phase, and amplitude. Using the sampling theorem, generate waveforms through table lookup. Figure 2 shows the basic circuit principle of DDs. The output of the phase accumulator is the phase of the synthesized signal. The digital waveform stored in the digital table is extracted using the lookup table method, and the analog waveform is formed through the D/A converter. The stepped wave output by D/A.
