“…So, one here represents the inverter end part of the variable, and 2 illustrates the grid side variables or measurable parameters. The H8 inverter configuration working principle is explained in [27]. Here, the converter output voltage before the filter and the filter capacitor voltage are represented in output current and voltage after the filter.…”

“…Hence, this paper is developed to consider power handling and independent active and reactive power flow controlling capability using a conventional H8 topology single-stage transformerless solar-PV cell inverter [27]. Here, the output from solar PV panel is directly connected to the eight switch inverter and is connected to a medium power rating grid directly.…”

With the rapid development in power electronics technologies and solar photovoltaic (PV) cells, the interest in solar PV cell-based electric power generation and other applications is increasing more incredibly. For low power grid or direct load applications, single-stage solar PV inverters without transformers are advantageous. Based on this concept solar single-stage eight switch H8 based transformerless solar PV inverter is proposed. The objective of the work is to present a control scheme for the H8 inverter to have better power handling capability and for independent active and reactive power control. For this, the test system is studied using MATLAB/ SIMULINK software under three cases (i) constant active power and varying reactive power, (ii) varying active power and constant reactive power, and (iii) varying both active and reactive power. The proposed inverter is compared with single-stage solar PV with two switches boost and six switches inverter topology. It is found that power flow ripples and surges are lesser for proposed H8 than with single-stage topology.
