## 1 Introduction
by the design of the compensation parameters in the CC mode. The third scheme can obtain CC and CV outputs that are independent of the load by using the PS control [12; 13]. However, for a wide range of PSs, the power switch's zero-voltage switching (ZVS) is not easily achievable, thus increasing the volt-ampere (VA) rating and the switching loss. However, these methods are complex and need real-time wireless communication links between the transmitter and receiver. In order to overcome the limitations of such control schemes, [PERSON] et al. [14] and [PERSON] et al. [15] developed a novel one by adding DC/DC converters on both sides of a traditional IPT system to control output by modifying the duty cycle. However, the increases in weight, volume, and system power loss caused by the DC/DC converter cannot satisfy the receiver's high-power density. Moreover, the foregoing control methods increase the difficulty of the control loop design. Considering these problems, another scheme that uses AC switches (ACSs) to promptly switch the compensated topology and obtain load-independent CC/CV outputs has been widely accepted because of its simple control scheme and low cost. The reconfigured compensated topology can be considered as a combo of different forms of passive resonance networks [16]. This scheme mainly includes the combination of low- or high-order hybrid-compensated topologies. The low-order hybrid topology mainly realizes load-independent CC and CV outputs by using different combinations of the four basic compensation topologies, i.e., series-series (S-S), parallel-parallel (P-P), series-parallel (S-P), and parallel-series (P-S) [17]. For realizing ZVS, the S-S and P-P topologies can charge the battery in the CC mode, while the S-P and P-S topologies can charge the battery in the CV mode under a dynamic load [18; 19; 20]. According to the four types of basic compensated topologies, [PERSON] et al. [21] proposed an IPT system with CC and CV outputs based on S-S and S-P topologies. [PERSON] et al. [22] achieved two CC/CV outputs by switching between S-S and P-S topologies. However, the limitations of the LCT parameters limit the design freedom of low-order IPT systems. To prevent the IPT system's output from being restricted by the LCT parameters, researchers have proposed a higher-order compensation topology composed of multiple compensation components. For example, the double-sided LCC (DS-LCC) and LCC-S compensated topologies utilize multiple interactive resonances of multiple compensation capacitors and inductors to implement CC/CV output characteristics, respectively [23; 24; 25; 26; 27; 28; 29; 30]. Higher-order topologies can achieve different levels of CC or CV outputs by adjusting the compensation inductance without changing the LCT. Therefore, [PERSON] et al. [31] proposed an IPT charger based on a combination of LCC-S and DS-LCC topologies to achieve CC/CV outputs while simultaneously achieving low reactive power and ZVS. [PERSON] et al. [32] proposed a variable-parameter IPT system with CC/CV outputs. Although only one ACS is used, a compensated capacitor is added, and a zero-phase angle (ZPA) is not implemented in the CC mode. An analysis of these models has indicated that the combination of low- and high-order compensation topologies usually adds additional reactive components, increases the weight, volume, and cost, and necessitates real-time wireless communication links. Moreover, to achieve CC and CV outputs, a complex feedback control link is typically added, increasing design difficulty. Therefore, a well-designed compensated network has significant advantages for realizing CC or CV outputs under open-loop conditions. However, ideas based on the secondary side involving the adoption of hybrid-compensated high-order topologies with near-communication have not been sufficiently investigated for realizing the CC/CV modes. In keeping with the foregoing discussion, this paper proposes a switching hybrid-compensated topology for the battery CC/CV charging mode on the secondary side.
