This paper presents a development of acoustic energy transfer (AET) system through air medium for low power application using Class E converter. AET system transmits energy in a form of wave through a couple of transducer that is driven by the power converter. The primary circuit of AET uses a Class E converter circuit to drive the non-linear load, which theoretically produces zero switching losses. To ensure that the power can be transmitted efficiently, an optimum frequency was generated by the power converter. The frequency was generated from pulse width modulation (PWM) using microcontroller. In this work, the maximum output power that can be transferred was 4.20mW at 39.68kHz frequencyReferences
