Analysis of cascaded multi-output-port converter for wireless plug-in Hybrid/On-Board EV chargers

This paper presents a new cascaded connection of multi-output-port converter for Plug-in Hybrid Electric and On-Board Electric Vehicles, which is suitable for dynamic wireless power transfer energy storage systems such as battery, ultra-capacitor, and load. In order to acquire the system power transfer integration between output ports, the central control stability is analyzed by phase shift function between converter ports. The theoretical calculation of the converter is explored describing the system model with a constant frequency under the different load conditions. The performance of the proposed converter is confirmed with experimental results using 8 inch air gap coreless transformer. The converter is tested at 120 V input and creates an output of 0-100 V and 0-50 V in each output port at a full power of 700 W.
