Fault-Tolerant Wireless Power Transfer System With S/S and LCC/S-Based Input-Series Output-Parallel Hybrid Topology
Typical faults such as open circuit (OC), short circuit, and abnormal coupling seriously threaten the safety of conventional wireless power transfer (WPT) systems, so fault tolerance is a critical design consideration for WPT systems, especially in high-power applications. This study proposes an S/S and LCC/S-based input-series output-parallel hybrid topology, with which WPT systems can tolerate typical faults and realize zero phase angle under normal operation. Considering common misalignment conditions, a receiver-side control strategy without dual-side communication is also designed for minimum fault current ratios and power sharing between the two subtopologies under normal operation, and a system design method for constant power output is then given. A WPT prototype with the proposed hybrid topology is developed, and the experimental validation is performed. The results show that the steady-state fault current is about two times the normal value under various faults, and the system can even operate with an abnormal close coupling or OC fault at the transmitting coil branch in the LCC/S subtopology.
