An interoperability enhancement strategy of WPT systems based on sensitivity analysis

Wireless power transfer technology represents a significant developmental trajectory for future charging infrastructure. As industrialization advances, the demand for cross-platform interoperability intensifies. Nevertheless, current research addressing interoperability between transmitters and receivers with disparate power ratings and parametric designs remains limited. Sensitivity analysis of compensation network components in wireless power transfer systems reveals that strategic parameter variations in specific elements can modulate current distribution patterns, thereby compensating for efficiency degradation caused by power rate discrepancies and impedance mismatches. Capitalizing on this insight, this study employs a switch-controlled capacitor to dynamically regulate the equivalent capacitance of critical components, significantly enhancing interoperability across various transmitter-receiver power specifications. Implementation of the proposed strategy consistently elevates transfer efficiency beyond 92.0% across diverse parameter configurations, confirming its substantial interoperability enhancement effect.
