Abstract |
This paper presents an output voltage model considering the eddy current loss of a magnetic substance attached to a transceiver coil for precise control of the output voltage of a wireless charger for (RX-Sensorless) mobility without sensors on the receiving side. In order to accurately control the reception-side output voltage by measuring only the physical amount of the transmission side, it is necessary to minimize the error of the output voltage model. Therefore, output voltage modeling is performed to reflect an eddy current loss of a magnetic body that affects the output voltage. The validity of the derived model is verified through simulation and experimental results compared with the existing model that does not reflect the eddy current loss. The analysis result shows that the error of the proposed model is reduced by up to 3.7% compared to the existing model. |
