“…This is explained by the fact that power losses in components and resonant circuits increase to a minor extent, compared to the transmitted power of the system. We experimented with a unidirectional system, based on the similar circuit solutions [27,37]. Load power was limited by a secondary power source in the transmitting part of the system and amounted to 133.45 W, whereas the maximum efficiency level was 76.47%.…”

This paper presents development of a circuit solution design for a bidirectional wireless energy transfer system, based on a resonant self-oscillator. The operation principle of the developed circuit solution in receiving and transmitting mode is described and the elementary circuit diagram is presented together with design ratios. Coil parameters for the resonant circuit are calculated, optimal number of turns in coils is presented, based upon the specified limit value of permissible current. The dependencies of system efficiency from transmitted power, maximum transmitted power, and energy transmission distance are obtained. The developed design, which includes the step-up DC-DC converter, allows to obtain the voltage on the output of the receiving system, equal to or higher than the voltage of the power source of the transmitting system. The specific feature of the proposed system is that it does not require a dedicated control system for operation in resonant mode and changing direction of power transfer. Resonance in transmitting and receiving coils can be maintained, even when their mutual layout is changed, due to utilization of identical resonant circuits and a self-oscillator. Application of the proposed solution is relevant for energy transfer among autonomous robots with limited positioning accuracy, as well as for energy transfer from power supply to robot or in reverse direction.

“…In the Table I, the initial parameters are given for selection of optimal turn number for the receiving and transmitting coils of low-power WPT system for further employment in swarm robotic system to redistribute energy among swarm agents [24]- [26]. Circuit and design solutions for the receiving [27], [28] and transmitting parts of WPT system are presented in our previous research, where the WPT system of moderate power is considered [29], [30]. Table II shows the results of theoretical calculation of parameters for the coil with turn number range from 1 to 20 by constant working frequency.…”

Correct choice of coil parameters for resonant circuits in inductive power transmission systems is a relevant problem, as it significantly influences the efficiency and transmitted power in the systems and provides for optimization of these parameters. This paper presents a methodology of calculation of geometrical and electrical parameters and approach to choose the optimal number of turns in planar coils used in the wireless power transmission (WPT) system with parallel resonant circuit. Formulas are derived for calculation of active resistance and inductance of the coil, normalized to the specified design parameters of the coil. Connection is made between the design and electrical parameters of the coil, which allows choosing the optimal number of turns according to different criteria and guard conditions. The examples of practical use of the chosen approach with transmitting and receiving coils of WPT system are presented. The obtained results show that efficiency and transmitted power in the system are higher when using the coils with the calculated number of turns. The proposed approach may be used in selection of optimal design of loop coils in systems with fixed frequency, and in systems, whose operational frequency depends on the parameters of the resonant circuit.

Приведен аналитический обзор работ, направленных на повышение длительности автономной работы БЛА и их обслуживание на сервисных наземных робототехнических платформах, в том числе в области сельскохозяйственной робототехники. При этом в зависимости от размера обрабатываемой территории, необходимой скорости реализации задачи и других факторов зависит количество привлекаемых роботов. Поэтому целью данного исследования являлась разработка математического и программного обеспечения рекомендующей программной системы, обеспечивающей оценивание состава гетерогенных робототехнических средств для выполнения сельскохозяйственных операций. Описан метод многокритериальной оценки количества и состава гетерогенных сельскохозяйственных робототехнических комплексов, необходимых для обработки заданной площади угодья, погодных условий и других аспектов, влияющих на стоимость и скорость выполнения работ. Представлена рекомендующая программная система AgrobotModeling, служащая для моделирования и визуализации процесса взаимодействия нескольких наземных сервисных платформ и беспилотных летательных аппаратов при обработке аграрных объектов.
