    Battery-equivalent DC supply from leakage current: PV to transformer-less inverter topology
    (Institute of Advanced Engineering and Science, 2016-12) Khan, M.N.H.,; Ahmad, K.J; Zahan, M.S.,; Hasan, M.N.
    Solar panels are highly used for electricity generation, which can be gotten through switching-based transformer-less inverters. Hence, grid system with no galvanic-isolation, is taking the peak level in the world, which is effective and delivers power with enhanced efficiency. The PV generation presented here is for stand-alone system installed in remote areas on when and as the resulting power gets connected to electronic load installation instead of being tied to the grid. In this paper will be discussed the use of leakage current. Transformer-less inverter topology for exploring the issue of common mode (CMV) voltage development, which can be utilized as a Battery-Equivalent DC Supply after adding on places as when found suitable for such installations. © 2016, Institute of Advanced Engineering and Science.

    Proposed PV transformer-less inverter topology technique for leakage current reduction
    (International Journal of Power Electronics and Drive Systems, 2016-09) Khan, M.N.H.,; Delwar, M.H.; Kabir, M.A.,; Zahan, M.S.,; Ahmad, K.J; Alam, M.M.; Anower, M.T.
    Importance and demand of using renewable energy is dramatically escalated globally. Hence, the use of renewable energy is going to touch in peak. This demand is varying according to the site choosing. For instance, Wind is preferable where air is following highly as well as solar recommended place is high sun ray reducing places. Especially, the renewable system is highly recommended for electrification issues where it’s possible to produce the electricity for fulfilling rural and remote areas electricity problem. The photovoltaic (PV) panel of connecting with transformer based system is popular where some limitations are occurred especially cost and weight. In contrast, in this paper is focusing these issues where the transformer-less inverter system is used. Here will discuss some transformer-based and transformer-less inverter topologies and the leakage current issue which is occurred when transformer-less inverter system is used. Moreover, here is proposed a topology for reducing the leakage current after doing switching technique in both 50% and 75% duty cycle where output voltage remains quite same. © 2016 Institute of Advanced Engineering and Science.
