Abstract
This study proposes a control structure combining charge current stability
control and optimal impedance tracking control to improve charging efficiency.
In which, an algorithm is given that plays the role of deciding the charging
current value for this control structure. The effectiveness of the proposed
structure is verified by simulation on PSIM. The charging current is controlled
stably with a response time of fewer than 0.01 seconds, the error does not
exceed 0.2%, and the system efficiency is improved up to 92.7%.
