    Abstract: A multi-frequency ultrasound therapy apparatus is configured to operate at its center frequency and at the higher harmonic of its center frequency. The center frequency can be for the entire apparatus or for each ultrasound source element. At least one source element can generate ultrasound energy at its center frequency while, simultaneously, at least another source element can generate ultrasound energy at the higher harmonic of its center frequency. In addition, the same source element can generate ultrasound energy at its center frequency and the higher harmonic of its center frequency, respectively, but at different times. A data storage unit that stores encrypted and encoded data is disposed on the apparatus. The encoded data includes a unique identification code of the apparatus, the condition of use of the apparatus, the center frequency of each source element, the ultrasound efficiency of each source element, and/or other parameters relating to the apparatus.

  • Publication number: 20200295568
    Abstract: A suppression method of high-frequency resonance for VSC-HVDC (Voltage Source Converter-High Voltage Direct Current Transmission) system based on nonlinear filter in voltage feed-forward control. It includes that the nonlinear filter is used for the voltage feed-forward link in the current inner loop control. The specific method is to extract each sequence component of the AC (Alternating Current) voltage, calculate the average value of the sequence component at N sample points, compare the current average value with the output result of nonlinear filter in the previous period, and output the result of nonlinear filter in the current period. After corrected, the result is a fixed value varying according to gradient which acts on the voltage feed-forward link of the inner loop.
