Abstract :
In order to regulate the output accurately, primary controller need to obtain the load voltage and current information via wireless communication or others in electric vehicle wireless charger. This paper proposed a novel control method via load detection technology. Firstly, through analyzing the current and voltage of primary coil, the equivalent input impedance of primary coil was calculated, and then derived the load detection equations to estimate the load information. Secondly, the control scheme was designed using PID strategy based on load information detected. Lastly, a simulation model was established to verify the proposed control method.
