“…MPPT algorithm isused for maximum power generation in PV panel and to utilize availability solar radiation effectively. Hardware implementation of DC-DC converter for MPPT in PV applications is given in [6]. In addition to this Zero voltage and soft switching [7] for non-isolated bidirectional converter is preferred for battery to interface with AC grid with reduced number of switches and high voltage gain.…”

The main objective of this paper is to propose the significant usage of photovoltaic modules in household applications. This paper describes a compact but fully functional design by integrating basic converters to form a simplified single inductor converter structure while keeping minimum number of switches. The resultant converter is fully reconfigurable that all possible power flow combinations among the sources and load are achieved through different switching patterns. Single inductor converter module is used to simplify the structure while reducing the number of switches. This is fully configurable enabling all possible power flow combinations. The experimental behavior of this module from morning till evening is observed and the wave pattern of the subjective proposed results are recorded and verified.

“…Many topologies have been proposed for step-up DC-DC converters, which in general can be classified into two categories: isolated topologies and non-isolated topologies [1]. The non-isolated step-up DC-DC converters include various boost type converters [2][3][4][5]. Their voltage regulation ratios can be further increased by using the cascaded [6] or coupled-inductor [7] technique.…”

Isolated converters are desirable in DC-DC power conversion applications where an isolation and/or a large voltage step-up gain is needed. The existing isolated DC-DC converters either utilise many switches to achieve high efficiency or use few switches which result in low efficiency. This study proposes a new single switch, isolated DC-DC converter with an LCL-resonant circuit. The proposed isolated DC-DC converter has the advantages of not only using the least number of switches (i.e. one switch), but also achieving zero-current switching when the switch is turned off. Experimental results are provided to validate the theoretical analysis of the proposed converter. Results show that the proposed converter has lower voltage stress and higher efficiency than the corresponding hard-switched converter.

“…Another solution that can be considered is obtained by connecting in cascade mode two or more converters, where each stage can provide a fraction of the desired voltage gain [17]- [19]. Disadvantages of this method are the high number of switch drivers and the complexity of the control if a high performance is required.…”

The best way to avoid MPPT drawbacks due to mismatching phenomena is to use a dedicated DC/DC converter, in charge of MPPT, for each PV panel instead of a big central converter for the whole PV array. Dedicated DC/DC converters can be boost-like converters; they must be serially connected each other to obtain an higher voltage as required by the grid inverter. However, when the number of PV panels is relatively low, the sum of the voltages of the boost converters in a string may be insufficient to allow the inverter energy conversion function. In this paper a non isolated interleaved switched inductance converter is proposed and studied. Such a converter is characterized by a high voltage ratio and by a quite simple construction. A mathematical study of static characteristics of the proposed converter in both CCM and DCM conditions is provided together with the analytical estimation of losses.Moreover, the proposed converter has been compared, in terms of losses, with the dual stage synchronous boost converter.
