Abstract

With the growing number of electric vehicles (EV), the demand for public charging infrastructure is on the rise. Due to the lack of standardisation of battery voltage and current levels, it is challenging to design and develop off-board chargers in a charging facility that can cater to multiple vehicles from different manufacturers. In this paper, a multi-port isolated active clamp boost Power Factor Correction (PFC) topology is proposed as a unified multi-port off-board charger for electric two-wheelers. The unified multi-port charger has three output ports, and thus it is able to charge three vehicles simultaneously. Also, each output port can cater to a wide range of battery voltage and current levels. Experimental results from a 1.2 kW hardware prototype are presented to demonstrate the operation of the unified multi-port charger.
