This study presents the modeling, control design, and performance analysis of a DC-DC buck converter using state-space averaging techniques, which are essential in modern power electronics for regulating DC voltages in renewable energy and electric vehicle systems. The objective is to introduce the basic operation of buck converters and the need for voltage regulation through closed-loop control systems. A state-space averaged model simplifies the nonlinear switched dynamics, allowing effective analysis and controller design. The small-signal transfer function from the duty cycle to the output voltage is derived to support control development, with a focus on Proportional-Integral (PI) control utilizing frequency-domain methods. The PI controller is tuned for various phase margins and evaluated through Bode plots, step responses, and performance metrics, revealing trade-offs in overshoot, settling time, and steady-state error. Complete simulations verify the controlled buck converter's capability to maintain stable output voltage across significant input voltage variations. The results validate the effectiveness of state-space averaging in control design and emphasize the robustness of feedback systems in power electronic converters.
