With the development of power electronics technology, computer technology, and automatic control theory, as well as the development of industrial applications and the high requirements of human beings for products, the development trend of ultrasonic power supply in the future is mainly focused on the following aspects:

(1) High power factor, low harmonic pollution
With the wide application of power electronics technology in the industrial field, various power electronic equipment and nonlinear loads are applied to the power grid, so that a large number of harmonics are injected into the power grid. The design of the ultrasonic power supply should focus on improving the power factor and improving the overall efficiency of the system. Improve the environment of the power grid and reduce the harmonic pollution of the power grid.
(2) High power and miniaturization
With the development of industrial demand, the power and equipment volume requirements of ultrasonic power supply are getting higher and higher, in order to meet the needs of the development of ultrasonic power supply in all walks of life, ultrasonic power supply should develop in the direction of high power and miniaturization.
(3) High precision and high reliability With the development and wide application of single-chip microcomputers, DSP and FPGA, higher requirements are put forward for control accuracy and reliability, such as for ultrasonic cleaning, ultrasonic welding, frequency and power control a significant impact on the effect of the product. Therefore, high precision and high reliability have become necessary for future development.
(4) Intelligent and integrated
With the development of electronic technology, artificial intelligence, integrated circuits, and various processors, on the basis of meeting the basic functions of ultrasonic power supply, the man-machine interface control system is added to realize the fast, real-time, and reliable transmission of data parameters and status information, so as to adapt to the user’s remote monitoring and fault diagnosis of ultrasonic power supply. Intelligence and integration are also the future development trends of ultrasonic power supply.
