Abstract
Abstract: DC-DC Converters are the inevitable stage in a system to power-up an electronic device, as it is very prominent to obtain a regulated and constant dc-dc supply to most of the electronic devices. These dc-dc converters are supplied with the dc supply either given directly by dc sources like batteries or obtained by converting AC to DC supply. In the proposed project, firstly the single phase ac supply of 230V,50 Hz is boosted to 390V DC and concurrently the power factor of the supply is corrected in the Boost Power Factor Correction (PFC) stage using IC UCC28180 which constitutes the first stage of the project. Further, this DC voltage is given to the Forward converter where it is stepped down to 48V DC which is finally given to power-up the ventilator. The designing of both Boost and Forward converters is done and they are verified by simulating them in the MATLAB Simulink software platform. Hardware implementation with the designed values is done and the relevant waveforms are obtained.
