초록
Ultrasonic welder joins with a horn and a booster for amplification of the mechanical displacement. This coupling generates other resonance points at a frequency range lower than the piezoelectric material's resonance frequency. Therefore, frequency variation range through PLL control was proposed in order to prevent reaction to these resonance points.
