The purpose of the work was to analyze working parameters of the developed simulation model of a capacitive power transmission system. The main advantage of the developed system is the ability to work efficiently with the receiver's changing position relative to the transmitter. Based on analysis of the obtained results, it can be clearly stated that the goal has been met. Based on individual capacitances as a function of a relative position of the receiver, it can be concluded that the fluctuation of the transmission parameters of the system is acceptable and that it enables stable operation of the system. In addition, referring to the transmitted power and system efficiency as a function of the position of the receiving board in relation to the transmitting board, it can be shown that the elaborated system maintains a stable efficiency close to the assumed one in the entire working area. Moreover, the paper presents and discusses the waveforms of current and voltage of individual system components. The system has been designed so that it can work in both optimal and sub-optimal working conditions of class-E inverter for the considered working area. This assumption allows for a stable operation and relatively high transmission parameters regardless of the relative position of the receiving board. The test that has been conducted on the laboratory stand of the elaborated CPT system have proven the validity of assumptions made and the reliability of the The purpose of the work was to analyze working parameters of the developed simulation model of a capacitive power transmission system.

The authors of the work intend to continue research on the presented system. Presently, work related to the construction of the discussed system is in progress. Moreover, authors consider that the possibility of the application of feedback from coupling equivalent capacitance *Cs* and active resonance frequency regulation would allow multiple receivers to be supplied from one transmitting board. Undoubtedly, the proposed solution would be a significant contribution to the development of consumer electronics.
