In this work, an inductive wireless power transfer module powered by resonant converter is studied. The system consists of a zero voltage switching resonant converter and a rotary wireless power transmitter. The design of the rotary wireless power transmitter is presented. Simulation and experimental studies of the system confirm reliable operation of the power electronic converter with a wide range of loads. The zero voltage switching is maintained without significant adjustments in the switching frequency. This improves the system stability with variations in the air gap between transmitting and receiving modules or the magnetic coupling ratio. The studied system is suitable for powering loads placed on a rotating platform or other applications where the disadvantages of moving electrical contacts are undesirable.

The paper presents the design of a single-ended transistor zero-voltage switch (ZVS) parallel resonant DC-DC converter. Due to the use of a resonant inverter in the structure of the DC-DC converter, it is characterized by high efficiency and improved performance. On the other hand, due to the specifics of the power circuit operation, in the work, it is proposed to find the values of some of the elements of the circuit of the electronic converter to be carried out based on the application of optimization. To solve this task, various tools available in Matlab/Simulink have been applied, as well as author’s programs specially developed for the purpose. The use of a hybrid method for the design of power electronic converters, which combines analytical and optimization approaches, is justified in cases where there is no adequate design procedure. With the increase in the complexity of the power topologies and their possible modes of operation, difficulties arise related to their design such as: assumptions and limitations in conducting the analysis and the corresponding methodologies based on this analysis; high order of the differential equations composing the mathematical models; need for highly qualified specialists in the field of design. The proposed approach does not negate the classical design methods based only on analytical ratios determined by analysis of power circuits, but complements and develops them with innovative ones based on the application of computational mathematics and information and communication technologies.
