A boost dc-dc converter is one of the most efficient techniques to step up DC input voltage to a higher output DC voltage. The boost converter has many applications, such as in a hybrid car, battery charger and photovoltaic system, In this paper, the simulation of three stage boost dc-dc converter was carried out by using MATLAB/Simulink and also implemented in Hardware. The circuit is tested with variable input voltage and fixed common duty cycle for all the three switches at no load and loaded condition. The simulated and hardware output voltages are compared with theoretical results.
