With the rapid growth of electric vehicles (EVs) on the roads, the demand for efficient charging infrastructure has become paramount. The modular multilevel based converters stand out as a promising technology for multiport EV chargers. This article proposes a hybrid modular converter with a dynamic control strategy for multiport battery swapping station. Each phase of this converter topology has two sections, series switch parts and wave orientation portion (WOP). The series switch parts are connected to grid via transformer to extract energy for charging, whereas each WOP provides the multiple charging ports. This article uses a dynamic control methodology to balance the voltage of WOP during the charging process, which eliminates the DC-DC converters requirements as the batteries can be directly connected to WOPs. Thus, a charging station with optimize footprint and initial investment can be realized. The working principle and the developed dynamic control mechanism of proposed hybrid modular converter are verified using a threephase seven level experimental setup.
