Design and Implementation of Step Up DC-DC Converter with a Cascaded Quasi-Z Source Network
This paper proposes a new topology of quasiZ-source inverter(qZSI) which is used as step-up isolated dc/dc converter for residential fuel cell (FC) power systems .The proposed topology used is cascaded quasi Z source inverter and implemented using induction motor. The cascaded qZSI is derived by the adding of one diode, one inductor and two capacitors to the traditional qZSI. The proposed two-s...
متن کاملA New Structure of Buck-Boost Z-Source Converter Based on Z-H Converter
In this paper, a new structure for buck-boost Z-source converter based on Z-H topology is proposed. The proposed converter consists of two LC networks similar to the conventional Z-source and Z-H converters. One of the characteristics of the proposed structure is that, without any changing in its’ power circuit, it can be used in different conversions such as dc/dc, dc/ac and ac/ac. This unique...

متن کاملA New Intelligent Controller for Parallel DC/DC Converters
In this paper, the immune controller, is used to control the paralleled DC-DC converters. A PID controller is first applied and its coefficient is optimized using an intelligent (PSO) algorithm. Immune controller is then added to PID controller and an immune PID controller is formed. Two methods have been suggested to determine non-linear behavior of immune controller. In the first method, an e...
متن کاملA Repetitive Control- based Approach for Power Sharing among Boost Converters in DC Microgrids
In this paper a repetitive control (RC) approach to improve current sharing between parallel-connected boost converters in DC microgrids is presented. The impact of changes in line impedance on current sharing is investigated. A repetitive controller is designed and connected in series with current controller of the boost converters to control the switching signals such that by regulating of th...
