In this paper, an approach is presented for selecting compensation capacitances in resonance based multi-coil WPT systems that utilize switched capacitor compensation. The approach for selecting the compensation capacitors is based on maintaining operation within the split resonant frequency region while misaligned.

The Cuk dual resonance core (DRC) realizes overlapped dual resonance to regulate its output voltage. However, the DRC configuration was only applied to the Fibonacci switched-capacitor converter (SCC), series–parallel SCC, and voltage doubler. In this paper, the Cuk DRC is modified and then is extended to the Dickson SCC to form a multi-resonance …
