The front-end converter of inductive power transfer (IPT) systems typically requires a cascaded four-switch buck-boost (FSBB) converter to interface with distributed power sources at different voltage levels. However, different operating frequencies and non-fully-decoupled operation of the two-stage system pose challenges for implementing …

Constant voltage (CV) charging is an essential stage in battery charging within an inductive power transfer (IPT) system. However, most existing research primarily focuses on investigating CV output under various load conditions. When the coupling coefficient varies, the output voltage correspondingly fluctuates. …
