Abstract

Continuous mode changes during battery charging present a significant challenge for the application of inductive power transfer (IPT) in battery charging. Achieving constant-current (CC) and constant-voltage (CV) charging characteristics is crucial for its successful implementation. This paper proposes a variable static S-T/FC compensation topology based on switching state changes. It offers the advantages of being able to handle various load conditions, facilitating soft switching of the inverter throughout the operation process, and achieving CC and CV charging without changing the operating frequency of the system. The characteristics of the proposed topology were confirmed through a theoretical analysis. Additionally, a completely new parameter design method is proposed. The CC and CV characteristics of the proposed topology are verified through theoretical derivation and simulation analysis. Finally, a validation prototype is constructed to assess the feasibility and rationality of the proposed method, achieving a 3.5 A output current in the CC mode and a 70 V output voltage in the CV mode.
