| Summary: | With the development of technology, people′s life rhythm is accelerating, thereby increasing the frequency of using mobile phones and making the previous wireless charging solutions unable to meet people′s needs. Therefore, fast wireless charging solutions with high efficiency and low interference are desirable in people′s lives. DC/DC voltage regulation can achieve digitally controllable voltage, and is widely used because of its high efficiency and good stability. Based on the principle of DC/DC voltage regulation, this paper designs two fixed frequency voltage regulation schemes for fast wireless charging, theoretically derives parameter settings in the circuits, and finally implements them according to the designed schemes. Performance tests and model experiments validate the correctness and effectiveness of the theoretical derivations and scheme designs, and indicate the proposed schemes have important application value.
