초록

본논문에서는모바일로봇수준에적용가능한4판병렬용량성동적무선전력전송커플러설계를제안한다. 실용등가회로모델은전자기시뮬레이션과높은일치율을얻기위해커플러손실저항을포함한다. 각회로망의S-파라미터곱을통해커플러의전체S-파라미터를산출하였다. 실용등가회로모델과전자기시뮬레이션에서도출된전송계수를비교했을때, 최댓값은6.35 MHz에서0.86으로 높은정확도로일치하였다. 또한, 송신부와수신부의비정렬로인해전송계수가0으로급감하는음영지역이관찰되었으며, 이는상호커패시턴스가0으로수렴하는위치와일치함을확인하였다. 본연구결과를통해향후모바일로봇에적용하기위한무선전력전송시스템설계에서간섭및기생성분분석에기여할것으로기대한다.

This study proposed a design of a 4-plate parallel capacitive dynamic wireless power transfer (WPT) coupler applicable to mobile robots. The practical equivalent circuit model incorporated the loss resistance of the coupler to achieve good agreement with the electromagnetic simulations. The overall S-parameter of the coupler was calculated as the product of the S-parameter of each network.
When comparing the transmission coefficients derived from the practical equivalent circuit model and electromagnetic simulations, the maximum value exhibited excellent agreement at 6.35 MHz with a value of 0.86. Additionally, null-power points where the transmission coefficient decreased to zero owing to transmitter-receiver misalignment were observed, corresponding to locations where the mutual capacitance converged to zero. These findings contribute to the design of wireless power transfer systems for mobile robots, particularly for analyzing interference and parasitic components.
