Abstract

The invention discloses an efficient and energy-saving ultrasonic power supply, which belongs to the technical field of ultrasonic power supplies, and comprises an MCU control module, a bridged APFC module, a high-frequency inversion module and an automatic frequency tracking module, wherein the bridged APFC module, the high-frequency inversion module and the automatic frequency tracking module are electrically connected with the MCU control module; and the bridged APFC module converts alternating current mains supply input by the power supply module into high-voltage direct current, the high-voltage direct current flows into the high-frequency inversion module, and the MCU control module acquires a current conversion state of the bridged APFC module. The power supply adopts a two-stage control APFC and high-frequency inversion scheme, and since the output voltage of the APFC is pure direct current, on the one hand, the problems of low power factor and high power consumption of the existing power supply are solved, on the other hand, the problem of periodic overvoltage at two ends of a load caused by alternating current wave crests of the inversion stage is solved, and the influence on the service life of an ultrasonic vibrator due to accelerated depolarization is avoided.

Description

Technical field [0001] The present invention belongs to the technical field of ultrasonic power supply, and more particularly to high efficient energy-saving ultrasonic power supplies. Background technique [0002] Ultrasonic cleaning system or in the field of ultrasonic surface treatment, ultrasonic power supply is required to work with ultrasonic vibrators or arrays, and ultrasonic vibrators have the characteristics of resonant frequencies, and the existing power supply cannot be accurately operated under this frequency, so that electroacoustic The efficiency is low; while the existing power supply is considered for cost, the rectifier bridge rectifier + reverse stage two-stage structure is used, and the input of the inverse transformation is the rectified taro, which will cause the inverse transformation. That is, the voltage across the ultrasonic vibrator is overvoltage of the peak time at the input end, which has a large impact on the parameters of the ultrasonic vibrator, r...
