This paper proposes a single-phase seven-level inverter for grid-connected photovoltaic systems, with a novel pulse width-modulated (PWM) control scheme. Three reference signals that are identical to each other with an offset that is equivalent to the amplitude of the triangular carrier signal were used to generate the PWM signals. The inverter is capable of producing seven levels of output-vol...

This paper deals with the simulation of a unified series-shunt compensator (USSC) aimed at examining its capability in improving power quality in a power distribution systems. The USSC simulation model comprises of two 12-pulse inverters which are connected in series and in shunt to the system. A generalized sinusoidal pulse width modulation switching technique is

<span>An island is a section of the electrical grid that contains producing assets and loads are separated from main powered by these generators, such as solar systems, with voltage frequency maintained at nominal levels. It's worth noting concept islanding linked to time. When inverter detects an isolated activity for particular period time, compelled decouple general grid, according cri...
