N2 - Capacitive power transfer has received a lot of attention as one of the new wireless power transfer technologies due to the flexibility of the coupling structure, low standing losses, and low Electromagnetic Interference. However, the ability to deliver power degrades significantly with load variations and coupling misalignment. This degradation represents a serious issue for the emerging technology. In this paper, a switch-controlled capacitor (SCC) and a buck-boost DC-DC converter have been added on the transmitter side and the receiving side of the conventional system, respectively. The SCC provides a mean of compensation for the coupling variations while a variable duty cycle DC-DC converter is employed to mitigate the load variation effect. A 26 W system is modeled and simulated, utilizing actual component models for verification. Compared to a typical system, the proposed system could achieve constant output power against variations of ±75% in the coupling interface value and a wide range of load variations from 5 Ω to 1 kΩ.
