The SEPIC converter allows you to set a continuous voltage range to maintain a constant voltage output. This project addresses the importance of dc-dc converters and why SEPIC converters are used instead of other dc-dc converters. This project also goes into detail on how to control the output of the inverter with a potentiometer or feedback to show how it can be implemented in a circuit. From this project, one learns the optimization and control of the dc-dc converter. The circuits work best with a constant and specific input. Controlling input to specific subcircuits is crucial to meeting design requirements. The AC-AC conversion can be easily done with a transformer; However dc-dc conversion is not so simple. Voltage diodes and bridges are useful for reducing the voltage by a certain amount, but may be inefficient. Voltage regulators can be used to provide a reference voltage. In addition, the battery voltage decreases as the batteries are discharged, which can cause many problems if there is no voltage control. The most efficient method of regulating the voltage across a circuit is with an dc-dc converter. There are 5 main types of dc-dc converters. Buck converters can only reduce voltage, boost converters can only increase voltage, and Buckboost, Cúk and SEPIC converters can increase or decrease voltage.
The DC-DC converter is a converter where we are regulating the input voltage to obtain the desired output voltage that is greater or equal to or less than the input voltage with positive or negative polarity. A large number of dc-dc converters are available in the world of which SEPIC (single-ended primary inductor converter) converter is one of them. To analyze the converter, there are many techniques available. This work presents the use of MATLAB / SIMULINK to study the stability of the converter. The state space technique is applied to this higher-order converter and becomes a transfer function. The reduced order technique is applied to the system and compared to the higher order system which provides approximate results for all types of analyzes.
