Abstract

In this era of globalization, the used of power electronics have increase widely due to high demand and applications of technology. On the other hand, the renewable energy sources become more important to the world with the depletion supply of oil and gas, coal and others. The renewable energy such as solar energy has its own speciality and can converts to electricity with the uses of the power electronics devices. The step up DC to DC converter is one of the popular devices in recent years. The main objective of this project is to study, simulate, analyse and design a step up DC to DC converter with 12V dc supply which is from the PV panel and produces a high voltage output which in range of 600V to 700V. The high output voltage will then be connected to multilevel inverter in order to converts DC to AC voltage for the transmission grid system. The step up DC to DC converter used in this project is Full-bridge converter. The software used to design, simulate and analyse the circuit simulation model is MATLAB/Simulink software. The open loop and close loop simulation circuits have been designed in the MATLAB/Simulink software. The close loop system uses the Proportional Integral (PI) as a controller to control the duty cycle of the Metal Oxide Semiconductor Field Effect transistor (MOSFET) to get the constant output voltage.
