High power factor, high frequency single stage single switch resonant inverter for the application of high frequency applications is presented in this paper. The power circuit is designed with a power factor corrector with single-switch current-fed high frequency resonant inverter. Number of switches used in conventional ballast circuits is reduced in single switch approach. SEPIC (Single ended...

The goal of this work is to reduce the DC-link capacitance of a two-stage single-phase inverter so much that the use of film capacitors becomes feasible in both, price and volume. Film capacitors instead of electrolytic capacitors could increase lifetime and reliability of the inverter, especially in high-temperature applications like module-integrated micro-inverters. For the capacitance reduc...

This paper presents optimal design of three-phase multilevel inverter for distributed power generation system using low frequency modulation and sinusoidal pulse width modulation as well. It is a modular type and it can be extended for extra number of output voltage levels by adding additional modular stages. The impact of the proposed topology is its proficiency to maximize the number of volta...

In Integrated Circuit industry power has become a major contribution. The main attribute is the clock power in circuits of VLSI. In today’s VLSI design scenario, power utilization by clocking takes up a vital role especially in design that uses deeply scaled CMOS technology. Proficient power utilization tends to be an important constraint in modern IC design. The underneath idea of multi bit fl...

136 Abstract— This paper presents a single-phase, single-stage current source inverter (CSI) based photovoltaic system (PV) for grid connection. A double-tuned parallel resonant circuit is designed to attenuate the secondand fourthorder harmonics at the inverter dc side. It helps to improve the power quality and system efficiency. A modified carrier based modulation technique for the current so...

Abstract Inverters play a significant role in the configuration of grid-connected photovoltaic (PV) systems. The perturb-and-observe (P&O) algorithm is common method to derive maximum power from inverters; however, possibility losing due sudden changes radiation drawback this control strategy. To overcome barrier, two-stage multi-string inverter using ZETA DC–DC converter and novel P&O ...

Switched Boost Inverter (SBI) is a single stage DC to AC power converter and it is derived from the Z source inverter employs an LC impedance network in between the main inverter bridge and the power source. This SBI converter can possible to supply both DC and AC loads simultaneously from a single dc input source. Here, reducing the inverter switching stress. Also, this converter provides to s...

Recently multilevel buck-boost Z-source inverter (ZSI) has been developed for better efficiency and power quality in renewable energy system. The impedance network of the Z-source inverter requires equal inductors and equal capacitor...

data envelopment analysis (dea) is a method for measuring the efficiency of peer decision making units (dmus) with multiple inputs and outputs. the traditional dea treats decision making units under evaluation as black boxes and calculates their efficiencies with first inputs and last outputs. this carries the notion of missing some intermediate measures in the process of changing the inputs to...
