Analysis, design and implementation of a residential inductive contactless energy transfer system with multiple mobile clamps

Abstract

This study presents the analysis, design and implementation of a simple and cost-effective residential inductive contactless energy transfer system with multiple mobile clamps. The topology is based on the cascaded connection of a buck converter and a high-frequency resonant inverter loaded by several output passive rectifiers. The proposed system includes a sliding transformer to supply the mobile loads, leading to a safe and flexible location of loads. The theoretical analysis and design of the proposed system is based on a mathematical model derived using the first harmonic approximation. Selected experimental results are included to verify the system features. In comparison with conventional topology, the proposed system significantly improves efficiency, complexity and cost.

Design of LCC-P Constant Current Topology Parameters for AUV Wireless Power Transfer

“…Compared with wired charging technology, it has the advantages of safety, concealment, and strong environmental adaptability [2,3]. It has been widely used in electronic devices [4], electric vehicles [5], and autonomous underwater vehicles (AUVs) [6][7][8][9]. The energy supply problem of AUVs greatly restricts the endurance and working range of AUV.…”

An LCC-P Compensated Wireless Power Transfer System with a Constant Current Output and Reduced Receiver Size

“…Wireless Power Transfer (WPT) technology is growing in popularity in recent years due to its non-physical connection between the source and the load [1][2][3], and it has been widely used in diverse scenarios, such as toothbrushes, cell phones [4], electrical vehicles [5], and autonomous underwater vehicles (AUVs) [6][7][8]. Energy is a major factor restricting the long-term continuous operation of the AUV in the ocean.…”
