用于无线电动汽车充电器中金属与活体对象检测的双模异物检测系统

Accurate detection of metal objects (MO) and live objects (LO) is essential to ensure the safe operation of wireless electric vehicle chargers. This letter proposes a dual-mode foreign object detection (FOD) system. The system utilizes the time division multiplexing mode to detect foreign objects and the frequency sweeping resonance mode to distinguish between MOs and LOs. First, a bipolar overlap...
