Aim of this project is to analyze the stability of single phase full bridge converter with reduced dc link capacitance. This can be done by replacing electrolytic capacitors by film capacitors. This will increase the reliability of the system and decreases the capacitance. This project compares both LTP and LTI model by considering the control gain and dc-bus capacitance size. The conventional linear time-invariant model may not represent the real converter behaviour. Hence it will lead to poor system performance or instability. Hence,the linear time-periodic model is highly encouraged for stability and transient analysis. The stability is analyzed using a Atmega 328 micro-controller. In this way, for any of these cases, the Linear Time Periodic (LTP) model are highly encouraged for stability and transient analysis as a tool for controller design.
