The four compensation capacitors are divided into parallel capacitance team and series capacitance team, and the work mechanism of the compensation capacitance on the output power, efficiency and the terminal voltage of the system are deeply analyzed. Then, the optimization approach based on Bayesian is given.
Similar to the current stresses across coupling coils, the voltage stresses over compensation capacitors are obtained and tabulated in Table 3. In general, the voltage stresses of LC/CL topology are lower than those of SS. Table 3. Voltage stresses over compensation capacitors for LC/CL and SS compensation topologies
There are four basic compensation topologies: SS, SP, PS, and PP where the letters ‘P’ and ‘S’ stand for the way how the resonant capacitor is connected to the coil, that is, ‘P’ represents parallel connection and ‘S’ represents series connection [ 14 ].
The power loss comes from switching devices, compensation components, and interface plates. As shown in Fig. 15, nearly 50% power loss is consumed in the parallel capacitors. Therefore, high-power capacitor with lower dissipation factor should be used in the CPT system in the future.
To improve the coupler misalignment performance, this study proposes an LC–CLC compensation topology for high-power and long-distance capacitive power transfer system. The LC circuit in the transmitter and the CLC circuit in the receiver are adopted as the resonant tank for the capacitive coupler.
The power transfer from the capacitive coupler can be calculated as P = ωCMU1U2 sin φ ; therefore, high switching frequency and high voltage are required to achieve high power transfer with the small coupler mutual capacitor CM .
