Ultrasonic Cleaner: Assessment for Different Modulation Technique
Abstract
system. Micro-controller is used for the generation of different pulse patterns i.e. PWM (pulse
width modulation) and PDM (pulse density modulation). Ultrasonic transducer drivers are driven
with the help of these control patterns by feeding it into the full bridge inverter.Efficiency of the
ultrasonic transducer is tested with the 22 kHz 100 watt resonating frequency. The waves
generated by the transducer, drives electrical force into the mechanical force. Due to the
movement of the ultrasonic waves into the aqueous solution in cleaning process cavitations and
inward bursting are occurred in liquid.
Keywords: Cavitations, resonant frequency, PWM, PDM, ultrasonic transducer
