A Multimodal Modulation Scheme for Electric Vehicles’ Wireless Power Transfer Systems, Based on Secondary Impedance

This study aimed to investigate a multimodal modulation scheme that takes into account the wide range of output characteristics, numerous constraints, and complex working conditions in wireless charging electric vehicles. Key electrical parameters variables secondary stages vehicle power transfer (EV-WPT) systems were evaluated based on capacitive, inductive, resistive impedance modes. The limiting duty cycle values, D, rectifier derived by detecting mutual inductance, M. was adopted, equivalent phase, control condition and, hence, achieve optimal performance. proposed method can modulate system performance before during transmission. verified using 10 kW EV-WPT experimental prototype under capacitive mode with 8.5 output. Our achieved full modulating conditions.
