Abstract
In this paper, a high frequency contactless power transfer (CPT) system is designed with ∅2 inverter drive. This system works in 30MHz frequency and 380W power with low voltage stress and considers the inductive link parasitic capacitor effect. In the design, we formulated the inverter equations first and then suggested another design for the transmitter and the receiver coils as the energy transfer medium. Following the inverter equations, structures of proper coil are designed for a CPT system. The results of the coil and ∅2 inverter designs are implemented as a bipolar circuit model which is equal to considering the inductive link parasitic capacitors. The system characteristics such as the stress, efficiency, mutual induction, field scattering, magnetic field distribution and the parameters’ variations are evaluated along with analysis. The results demonstrate that the presented CPT system has high efficiency, low switching voltage stress, small passive energy storage elements and fast dynamic response.
