WIDE INPUT WIDE OUTPUT DC–DC CONVERTER

Aniruddh Kashyap

Abstract


Wide Input Wide Output (WIWO) DC-DC converter is a combination of buck and boost converters through a coupled inductor. It has an output voltage that is either greater than or less than the input voltage. Step down and step up mode is switched by a proper control scheme. The WIWO will minimize the input voltage 48 Vdc to 19 Vdc also maximize the input voltage 48 Vdc to 230 Vdc with the switching frequency 67 kHz for buck and 2 kHz for boost. The simulation software used for simulation of WIWO converter is MATLAB SIMULINK.
