Abstract: The utility of electric power plays a major role in economic development of a country. However, the demand for electrical energy goes on increasing every day. In order to meet out the demand for electricity, Renewable Energy Source (RES) has been identified as the alternate for electricity generation. Among the various RES, PV system has added consideration throughout the world due to its easy accessibility, boundless nature and of low maintenance cost. Since the voltage obtained from PV is not suitable for high power applications, a DC/DC step up converter is introduced. This converter should have reduced output voltage ripple which is an important factor that influences the overall performance of PV system. Hence, this work studied about the different topology of converter suitable for PV systems to have a better efficiency.

“…According to some statistics, using resonant converter is growing immediately in power electronics. Resonance converter can be utilized in different cases, such as LED drivers, 5 HF inverters, 6 electronic ballasts, 7 battery chargers, 8,9 motor drive, 10 multilevel converters, 11,12 LCD TV power supply, 13 renewable energy, 14,15 and even for Maglev due to high performance of these converters. 16 In Wan and Yang, 17,18 a general grouping of this type of converter has been stated: series resonant converter (SRC), parallel resonant converter (PRC), and series-parallel resonant converter (SPRC).…”

Summary In this paper, a new design procedure for LLC converter has been introduced. In fact, this method is a computer‐based design algorithm based on a numerical technique. In the process of designing, the value of the resonant element is obtained by solving the LLC converter fundamental equation. This converter will be controlled by using state feedback, such as output voltage variable. As a matter of fact, in a control system, the change of output voltage (because of load variation) will affect the switching frequency, so the output voltage will be tuned. In the designing process, the fundamental equations of LLC converter are obtained, and the value of the resonant elements is calculated. Also, a comparison analysis is carried out between the proposed and typical methods. The simulation is done to investigate the validity of the proposed method. Moreover, a prototype is manufactured, and the experimental test is done to evaluate its applicability.

Summary In this paper, a simple non‐isolated multiple input (MI) bidirectional DC‐DC topology is proposed which can operate in buck, boost, or buck‐boost modes. The proposed topology utilizes a battery pack to realize the bidirectional power flow operation especially when the input sources are non‐storable ones. The excess energy of input sources can be stored in the battery and be injected to the load, when required. Simultaneous or independent power transfer of input sources is also provided. For better evaluation, the proposed topology has been compared with several recently presented novel topologies, from view point of number of inductors, capacitors, switches, and diodes. Comparison results show that the proposed topology utilizes less number of components (switches, inductors, capacitors, and current sensors) which can reduce the size, cost, and complexity of converter. Different operational modes of the proposed topology (unidirectional buck, boost, buck‐boost modes, and bidirectional mode) have been presented. Also, boost mode of the proposed topology has been investigated in detail, from design point of view, and generalized relationships have been proposed for calculation of critical inductance (CI) and output voltage ripple (OVR) of proposed n‐input boost topology. To validate proposed theoretical concepts, the proposed topology has been modeled and simulated in PSCAD/EMTDC software, and the 3‐input boost version has been experimentally implemented. Simulation and experimental results confirm appropriate performance of the proposed topology.
