Project Code :TEMAPE76

Objective

The main objective of the project is to achieve high voltage gain and low switch voltage stress.

Abstract

In this project, a high step-up DC-DC converter is proposed to obtain higher voltage gain and lower switch and diode voltage stress. With magnetic-coupling based voltage multiplier technique, the proposed converter achieves high voltage gain and low switch voltage stress.

Also, due to a boost inductor at the input, continuous input current is obtained, which is beneficial for battery, fuel cell and photovoltaic applications. Moreover, zero voltage switching of the MOSFETs are achieved, leading to low switching losses.

Furthermore, zero DC bias of the coupled inductor is realized, resulting in small magnetic size and low core losses. The operation principles, performance analysis and design considerations of the proposed converter are discussed. The proposed system is modeled in MATLAB/Simulink.

Keywords: Coupled inductor, continuous input current, high gain, high step-up converter, zero dc bias, zero voltage switching.
