Abstract
To ensure the stable and efficient charging of the wireless charging system in the misaligned environment
an LCC-LC/S compensated wireless charging system with anti-misalignment characteristics is proposed
which requires neither primary-side nor secondary-side communication
requires few components
and has good anti-misalignment effect.Firstly
the two-port network is used to optimize the design of the compensation network structure
enabling the system to maintain load-independent constant output gain and zero phase angle(ZPA) characteristics even in a coil-misaligned environment.Then
an LCC-LC/S variable-structure compensation network is proposed
and the parameter configuration conditions and output characteristics of the system in different modes are analyzed.Secondly
smooth switching of the system is realized by analyzing the switching point between constant current and constant voltage modes.Finally
a simulation model is established.By comparing with the widely used series-series/parallel (S-S/P) network
the good anti-misalignment characteristics of the proposed system are highlighted
