Independent Active and Reactive Power Control for Single Stage H8 Transformer-less Solar PV Inverter

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