Prototypes of wireless power electronics interfaces for efficient energy transfer

Development of wireless power transfer with special emphasis on the efficiency of inductive power transfer and ultrasonic power transmission systemsBoth approaches mentioned above are using a set of a transmitter and one or multiple receivers to transmitelectrical energy over some distance with no physical connection in betweenIn the first section of this deliverable we propose a novel method of designing power inverter circuits for driving the primary coil of the transmitter in an inductive wireless power transfer system The main goal or our designing algorithm is experimental accuracy multilevel circuit properties control and high efficiency operation In the next section we test the limitations of the commercial ultrasonic transducers as an acoustic wireless power transmitters and receivers to understand the potential of this technology for powering Wireless Sensor Network WSN Two transducers MA40S4S and MCUSD40A100B17RS70C with differing frequencies were used in the experiments to understand the absorptive and geometric attenuation of sound waves in air
