Designing A SEPIC Converter



Introduction

In a SEPIC (Single Ended Primary Inductance Converter) design,
the output voltage can be higher or lower than the input
voltage. The SEPIC converter shown in Figure 1 uses two
inductors, L1 and L2. The two inductors can be wound on the
same core since the same voltages are applied to them
throughout the switching cycle. Using a coupled inductor
takes up less space on the PCB and tends to be lower cost
than two separate inductors. T ....etc

With these files it is possible to calculate and simulate a dollar, a boost or a buck-boost converter. There is a .m file with the design parameters (Init.m), that the parameters can be changed by the usser, and to simulate the converters this file must be executed previously. On the other hand, there is a matlab function with calculations (this file is called from Init.m).
Finally, there is a model of the three converters. It is possible to add a controller to the model or change the type of load (in the attached file it is considered a resis ....etc

Hi,
I'm an electrical engineering student and would like to control a Sepic converter using fuzzy logic on MOSFET switch. I use matlab / simulink. I already have almost everything ready, the problem is that I can t find the right inference rule to stabilize the control in 9,6V being that the input source is a solar panel ranging from 5 to 15,5V. Do you have any rule to Sepic logic control using fuzzy logic? Even a surface chart serve. Or a fuzzy simulation file type fis.. Thank you. ....etc

Since the fuel cell system has slow dynamics of nature, it is recommended that you have an additional auxiliary power, for example, ultra-capacitors or batteries during the transition to improved performance in energy and transport applications. The use of ultracapacitors and bi-directional converter with a fuel cell system may be one of the possible solutions to the problem of slow dynamics of fuel cell systems. In this article we present a combined small AC signal equivalent circuit model of bidirectional converter in PEM fuel cell, and the c ....etc
