Self-decoupled coupler based dual-coupled LCC-LCC rotating wireless power transfer system with enhanced output power
This paper proposes a rotating wireless power transfer system with dual-coupled LCC-LCC topology based on a self-decoupled rotary coupler for addressing the issues of wear and short lifespan associated with traditional electric brush slip rings. In comparison to the conventional single-coupled LCC-LCC topology, the proposed system results in a significant increase in output power and a more compact structure. First, the dual-coupled LCC-LCC topology circuit system is analyzed. A self-decoupled rotary coupler incorporating two pairs of coupled coils is proposed. Second, through the utilization of simulation software, the effects of coil dimension, turns, and magnetic shielding on the self-inductance and coupling coefficients are analyzed, optimizing the coupler for compactness and miniaturization. Third, an experimental setup is established to validate the self-decoupled performance and power enhancement capabilities of the designed coupler. Experimental results demonstrate that, under positive conditions, the proposed self-decoupled coupler achieves a system transmission power of 62.54 W, which is 240% higher than that of single-coupled systems, albeit with an 11.2% efficiency decrease. This system is suitable for rapid charging in rotary applications.
