This paper deals with designing a simple and efficient simultaneous inductive power and data transmission for transcutaneous Micro-system based on ASK modulation at 6,78 MHz industrial, scientific, and medical (ISM) band to avoid the tissue damage. The modified ASK modulator and inductive coupling link driven by efficient Class-E power amplifier with 94,5% efficiency and the coupling link of up to 78,29% of efficiency are introduced to transmit 500 Kbit/s of data with modulation index 12,5%, modulation rate 7,37%. The proposed design is simple, easy to implement and able to power the bio-implantable devices with DC V up to 5 V. The mathematical model is given and the system is designed and validated by professional OrCADPsPice 16,6 environment simulation using a standard AMS 0,35 µm MOS technology. In addition, for real-time simulation, the electronic workbench MULISIM 11 has been used to simulate the class-E power amplifier switching. This design is useful for cochlear implants, retinal implants and implantable micro-system stimulator.

The thesis focuses on the study of the electrical component of the electromagnetic field, radiated by the wireless energy transfer system into the adjacent environment. The wireless energy transfer and the wireless data transfer are studied simultaneously, focusing on the appropriate wireless communication channel between the transmitter and the receiver, so to make that channel improved. An implementation of a wireless energy transfer experimental prototype that operates simultaneously with a wireless data transmission is assembled. A computational application that allows tuning the operational frequency of the prototype to correspond to the resonant mode operation is developed.

Abstract. This paper focuses on measurement and analysis of the electromagnetic fields generated by wireless power transfer system and their possible interaction on data transmission channel. To measure the levels of electromagnetic fields and spectrum near the wireless power transfer equipment the measurement system in the frequency range 100 kHz to 3 GHz was used. Due to the advances in technology it becomes feasible to apply the wireless power transfer in the electric vehicles charging. Currently, in the Faculty of Science and Technology of the University Nova high power wireless power transfer systems are in development. Those systems need to be controlled by several microcontrollers in order to optimize the energy transmission. Their mutual communication is of extreme importance especially when high intensity fields will generate highly undesired influence. The controllers are supposed to communicate with each other through radio frequency data channels. The wireless power transfer system with the electromagnetic interference may influence or completely disrupt the communication which will be a severe problem.
