An implementation of class D inverter for ultrasonic transducer mixed powder mixture
Ultrasonic transducers (UTs) are the main components for generating sonic waves. These types of transducers are nonlinear loads, and they are adversely affected by changes in mechanical load or temperature. UTs are operated in the region close to the resonant frequency.

| Summary: | Ultrasonic transducers (UTs) are the main components for generating sonic waves. These types of transducers are nonlinear loads, and they are adversely affected by changes in mechanical load or temperature. UTs are operated in the region close to the resonant frequency. An ultrasonic transducer needs to be driven by a high-frequency inverter. In this paper, a Class D resonant inverter circuit is implemented for ultrasonic mixer application. The proposed circuit operates at 34306 Hz at 140 V and has low cost and size. The simulation results of Class D inverter verified with the prototype experimental circuit. Al (Aluminum) alloy with ethanol and graphene is mixed in order to show the mixing performance of the resonant inverter fed transducer with probe. The system achieved the fine particles and homogen mixture according to the SEM images and EDX analysis. |
