Feedback Effect for Wireless High-Power Transmission
Authors: , , ,
Abstract: Wireless power transmission is based on electromagnetical phenomenon between two separate coils. In order to transfer power from one to the other, we have to cause a time-varying current along one coil. Many of conventional wireless power transmission systems suppose a sinusoidal current of the coil. One reason for it could be the convenience that we have a sinusoidal power source as the industry standard. If we can use a power source which generates many types of wave form, we do not necessarily use the sinusoidal wave. In this study, we propose to add a feedback signal on a sinusoidal signal, that is, we propose to utilize a non-sinusoidal input. We will evaluate the sinusoidal wave and non-sinusoidal wave from the viewpoint of transmission power and efficiency to secondary side.
