The Circuit Analysis and Performance Evaluation of an Hc Type Magnetic Coupling Contactless Power Transformer that is Compatible with Both Solenoid and Circular Type Transformers

Abstract

SUMMARYThere are two types of the transformers in a contactless power transfer system: solenoid type (H-shaped) and circular type transformers. These two types of transformers are not compatible because their magnetic field structures are different. An Hc type transformer that is compatible with both transformer types has been proposed. The Hc type receiver adds a central magnetic pole by dividing the winding coil of the H-shaped receiver. The Hc type receiver can change the magnetic field structure by changing the connections of the divided windings and can receive power from both types of transmitters. In this study, we conducted a circuit analysis and evaluated the performance of the Hc type transformer.
