Abstract
This paper discusses the challenges in developing a high-efficiency driver circuit for an
ultrasonic cleaning system. The main issue lies in finding the suitable driver circuit and drive signal to
ensure the correct frequency level for the ultrasonic transducer. This difficulty affects the removal of
contaminants from inaccessible areas due to the inability to control cavitation bubbles. To address these
problems, the authors studied the behaviour of piezoelectric transducers and designed driver and output
power circuits. The LTspice XVII software was used to design and simulate various circuits, and it was
found that trapezoidal pulses were the most suitable drive signals for avoiding power loss and achieving
reasonable efficiency. The generated output frequency of 38.6 kHz provides sufficient energy for cleaning
various small metallic items like jewellery, wristwatches, glasses, etc. The findings of this study will be
helpful for those conducting research in this area in the future.
