The impedance network of the proposed topology maintains the same number of components count and inverter outcome similar to traditional MCA-ZSI. The key advantages of the proposed topology are the reduced voltage stress on the main components of ZSI impedance network, i.e., capacitors. Besides, the inrush start-up current also reduced for the series connection of the whole impedance network from input DC side to output AC side. Moreover, the proposed topology provides a common ground which can help to reduce the leakage current in the photovoltaic application. For the common ground sharing feature, which is not available in the conventional MCA-ZSI, the SMCA-ZSI topology can be categorized as a doubly grounded inverter topology. The improved performances of the proposed SMCA-ZSI have been demonstrated by simulation results which are performed in Matlab/Simulink software. © 2019 IEEE. %Z cited By 4; Conference of 4th IEEE Conference on Energy Conversion, CENCON 2019 ; Conference Date: 16 October 2019 Through 17 October 2019; Conference Code:157290
