Abstract

Background: Conventionally, a two-stage conversion is required for providing isolated DC output.

Objectives: This paper aimed at proposing a converter comprising three ports with isolated output and higher output power and voltage levels, and to study its switching operations.

Methods: The converter has two input ports that connect an AC source and the solar PV source. The third port acts as an output port to supply the desired load. The proposed topology can supply the high dc output voltage with isolation while maintaining a high input power factor. A singlestage conversion is used in the converter, which helps in reducing the switching devices and the bulky electrolytic capacitor while integrating a solar PV. As there is no intermediate stage of conversion in the proposed converter, it is well suited for the standalone PV-based applications, such as remote light electric vehicle chargers.

Results: The simulation verification of the proposed converter has been obtained in the MATLAB/SIMULINK, and the experimental results have been obtained via a control algorithm implemented using FPGA-based Typhoon HIL 402, which demonstrated the control method and working of topology to be effective.

Conclusion: The desirable operation of the converter has been achieved.

Keywords: AC/DC converter, Power factor correction, isolated, three port, Single-stage, PFC
