This paper proposes a diamond-shaped high step-up switched-capacitor based basic multilevel inverter topology. The (SC) stage consists of 2 active switches, diodes, and capacitors. Using single DC source with the unfolding circuit (10 5 capacitors, diodes) results in production 17 voltage-steps at output gain up to 8 times input voltage. By extending stages, higher voltage levels gains can be p...

A non-volatile nanocrystal floating gate MOS capacitor with multi-level function is achieved by engineering the electric field within the tunneling oxide via a stepped control oxide. A MOS capacitor containing Au nanocrystals in a stepped HfO2 and SiO2 tunneling oxide matrix was fabricated in order to demonstrate this concept. The flatband voltage shift, measured from the C–V hysteresis curves,...

This paper presents an efficient approach for optimal placement of capacitor in radial distribution system, with an objective of improving the voltage profile and reduction of power loss. Distribution system is a link between high voltage transmission system and the low voltage end users, so it’s very essential to keep the system healthy and with minimum losses. The present work is devoted to d...

According to nonlinear operation of STATCOM, nonlinear controller has a better performance in comparison with linear controller. Regulating the DC capacitor voltage in STATCOM is a common task and can improve the system dynamic. The nonlinear control is based on exact linearization via feedback. A PI controller exists in this control system to regulate the capacitor voltage. In conventional sch...

The recent explosion of interest in wireless personal communication systems motivates the development of fully integrated radio receivers. The parallel reduction of the feature sizes in CMOS technology, and hence higher levels of integration. enable the combined integration of a bandpass or baseband analog-to-digital converter with the traditional front-end receiver building blocks.
