| Summary: | Since 2010,wireless power transfer(WPT) standard Qi has been introduced. Wireless Power
Consortium(WPC) have been expanding to WPT applications into mid-power and high-power
realms, including electric vehicles(EV)charging. Fast charging technology offers a solution for
users to quicky charge their devices such as electric vehicles(EV).By using of wireless power
transfer system, user can charge cable-free while achieving faster charging times, enhancing
overall user experience, and increasing productivity.
However, implement of this system in the medium power applications poses its unique challenges
such as optimizing efficiency ,managing heat dissipation, and maintaining safety standards.
Therefore, we need to develop a solution to simulate and overcome such challenges.
For this project, a dual active bridge converter and a PI controller will be designed to supply an
optimum constant current to ensure that the battery will not be overheating when charged at the
current and ensure fast charging is achieved. PI controller is used to generate the duty ratio for
the switching component to achieve a change in constant current. |
