In this paper, we conducted research on the comparison and application of topologies for driving a wireless power transmission device with a linear motor. Prior to designing the power converter, we measured the impedance of the wireless power transmission system and performed simulations through equivalent circuit modeling according to the impedance. By analyzing the frequency response characteristics, we selected the target voltage gain and extracted the parameters necessary for configuring the resonant circuit. Additionally, an analysis of resonance topology, which is important in resonant circuit design, was conducted. Through experiments, we analyzed the characteristics of S-S and S-P topologies and selected a topology more suitable for the wireless power transmission system studied in this paper.
