This project focuses on the design, simulation, and hardware implementation of three popular types of DC-DC converters: Buck, Boost, and Buck-Boost converters. The project includes MATLAB models for simulating the converters and hardware circuits controlled using an Arduino PWM controller.
The project comprises the following components:
-
MATLAB Models: MATLAB models are developed to simulate the behavior and characteristics of Buck, Boost, and Buck-Boost converters. These models allow for the analysis of voltage and current waveforms, efficiency, and transient responses under different load conditions.
-
Hardware Circuits: Physical circuits for the Buck, Boost, and Buck-Boost converters are built using electronic components. The Arduino board is used as a PWM (Pulse-Width Modulation) controller to control the switching operations of the converters.
-
MATLAB Simulation:
- Open the MATLAB models corresponding to the desired converter (Buck, Boost, or Buck-Boost).
- Set the input voltage, load resistance, and any other relevant parameters.
- Run the simulation to observe the converter's behavior and performance characteristics.
