Implementation of Mathematical Models of Buck Converter using MatLab/Simulink

The study of the dynamic behavior, transient response and the characteristics

of the converters require deep knowledge in mathematical models.

Mathematical models have been adequately used in the design and control of

DC-DC converters and also the mathematical models are more suitable than

the physical models. This paper describes the four modeling techniques of a

buck converter, circuit model, mathematical model, state space model and

transfer function model, and their implementation in Simulink environment.
