Abstract

The demand for wireless power transfer (WPT) systems that can maintain a constant voltage output (CVO)characteristic is gradually increasing in some practical application areas of WPT, such as industrial power supplies. However, existing CVO-type systems are often limited by the parameter design of the loosely coupled transformer (LCT) and the configuration of the receiver side is not compact enough. Therefore, this paper proposes a strongly coupled system with CVO function composed of capacitor-inductor-capacitor-none (CLC-N) topology. The system’s primary side uses a CLC compensation, while the secondary side conforms to a minimalist design without the need for compensation components such as capacitors and inductors. The initial segment of the paper pertains to the discussion of the conditions required to satisfy both zero-phase-angle (ZPA) and CVO functionality of the suggested system. Subsequently, an in-depth approach to parameter design is outlined, accentuating that the output voltage remains unrestricted by the LCT’s parameters. Additionally, this paper examines the realization of zero-voltage switching (ZVS) within the suggested system, as well as the influence that variations in compensation components have on the CVO function. To underscore the benefits of the suggested CVO-type WPT system that employs CLC-N compensation, the paper presents a comparison with a range of other CVO-type WPT systems. Ultimately, an experimental prototype is fabricated to test the theoretical framework, and the results from these experiments confirm the feasibility of the suggested CVO-type WPT system based on CLC-N compensation.
