A SEPIC DC-DC converter (Single Ended Primary Inductance Converter). The SEPIC converter allows you to set a continuous voltage range to maintain a constant voltage output. The SEPIC converter is used to overcome the limitation of the conventional dollar impulse converter as inverted output, pulsating input current, high voltage voltage make it unreliable for the wide range of operation. The MATLAB simulation is used to validate the method and show the efficiency of the design.
A lot of dc-dc converter has been designed for different application purposes such as buck converter, boost converter, buck-boost converter, flyback converter, push-pull converter, forward converter etc. The converters are designed on the basis Of the switching operation helping To transfer the power from the load to the source. The SEPIC converter is one of the dcdc converters that gives greater or lesser output voltage as compared to the input voltage with the aid of the switching operation and energy storage elements as inductor and capacitor. The mode of operation of the converter depends on the flow of the charge current which may be continuous or discontinuous. Therefore, the inverter can operate as a continuous drive mode (CCM) or a discontinuous drive mode (DCM) depending on whether the load is heavy or light. The switching operation takes place at a higher frequency which increases the system response. When designing any converter, we have to consider the source, switching elements, filter elements and loads. The filter elements are mainly the energy storage elements that decide the order of the system. For lower order converters, it is easier to design converters that can operate in stable mode and the design of the controller is also simple. For higher order converters, it is very difficult to design the controller that can operate the converter in stable mode. The SEPIC converter is a 4th order converter where two inductors and two capacitors are used. Since the system is non-linear, the design of the controller is very difficult. To analyze the behavior of the system, the order of the system must be reduced using well-defined methods. It can be understood in the following video: |
