This paper presents a highly efficient three-port converter to integrate energy storage (ES) and wireless power transfer (WPT) systems. The proposed converter consists of a bidirectional DC-DC converter and an AC-DC converter with a resonant capacitor. By sharing an inductor and four switches in the bidirectional DC-DC converter, the bidirectional DC-DC converter operates as a DC-DC converter for ES systems and simultaneously as a DC-AC converter for WPT systems. Here, four switches are turned on under the zero voltage switching conditions. The AC-DC converter for WPT system achieves high voltage gain by using a resonance between the resonant capacitor and the leakage inductance of a receiving coil. A 100-W prototype was built and tested to verify the effectiveness of the converter; it had a maximum power-conversion efficiency of 95.9% for the battery load and of 93.8% for the wireless charging load.

“…Also the challenges found here is the unequal current distribution and increased power stages. Ripple reduction in input current and output voltage [14], reduced EMI filter [15], the phase-shedding that improves the efficiency at light load [16], the coupled magnetic utilization which results in raising the power density [17] helps in reaching higher power levels.…”

A non-isolated tri-port converter is a fully compact and functional system by the integration of basic converters. This can be used for renewable energy applications. This converter is capable of achieving different switching patterns of power flow between the source and load, interfaced sources of various voltage and current levels with the dc grid. This tri-port converter has to be used for continuous power distribution of rechargeable battery, photovoltaic panels and load. Due to the implementation of this dc-dc converter some operations like buck, boost and buck-boost operations became easy. Use of this converter helps in easy implementation of the system. The solar PV panel implementation boosts the system to a high level and bidirectional flow became easy from source to load and vice versa

“…However, this method will additionally complex the control of the switches on inductor which might increase the switching loss and EMI problems. In reference [8,9], the coupled inductor is introduced and used in interleaved CCM boost PFC converter. Although, the DC magnetic flux can be canceled in the coupled inductor.…”

This paper presents the designed method and the implementation of stepped air-gap ferrite inductor applied in power factor correction (PFC). Conventionally, the input inductor of the PFC has a designed consideration on the maximum output power; thus, designing the PFC for peak-power-load conditions results in a very large inductor. The proposed designed method improves the load-carrying capability without increasing the volume of the inductor when the PFC is operating in peak-power-load conditions. The stepped air-gap ferrite inductor maintains the inductance in the rated-full-load and sustains the peak-power-load conditions with the lower inductance. Compared with the convectional ferrite inductor, the proposed method can maintain the size and the efficiency of the power supply, and promote the powercarrying ability. The detailed analysis and the design of the proposed method are described. Experimental results are recorded and evaluated by a prototype PFC with an AC input voltage of 110-264 VAC and a DC output voltage of 384 VDC. Finally, the volume of input inductor is kept with 40950 mm 2 , the efficiency is also same compared with the conventional inductor, and the load-carrying capability of the converter is promoted from the normal rated power of 1 kW to the peak power load of 2 kW.
