With the increasing need for solar energy and DC-DC converters that are more efficient, smaller in size, less expensive, faster response, this paper, we will modify positive output super-lift Luo converter using a switched-capacitor cell. It consists of two capacitors charged parallel discharged series to raise voltage, use in-stead inductors increases because efficient have size than provide s...

The insufficiency and soaring rate of fossil fuels, as well growing concerns about global warming, have pushed electric vehicles (EVs) to become a significant aspect the future transportation system. growth in adoption EVs results need for broadly spread charging stations, hence Photovoltaic (PV) based EV system is adopted since generation power from PV possible everywhere. An with two converte...

This paper proposes an improved control method based on modified Delta-Sigma Modulator (DSM) to enhance transient response and improve harmonic contents of buck DC-DC converter. The main advantages of the proposed method are improving the output voltage frequency spectrum, correction of the output voltage harmonic contents and sideband harmonics, reduction of switching noise peaks at the output...

DC-DC converters form a class of highly nonlinear systems and are widely used in most practical applications. Positive Output Elementary Luo Converter (POELC) is fourth-order converter to regulate dc voltages low power applications with varying input voltage load conditions. POELC employed for sensitive like SMPS, powering hard disks etc. The control higher-order always challenging task due the...

In this paper direct AC to DC is converted by proposed model from low AC voltage to high DC voltage in single stage conversion. And this paper presents an efficient AC to DC power that avoids the bridge rectification and directly converts low AC input voltage to high DC output voltage. This proposed converter consists boost converter and buck-boost converter both are connected in parallel to pr...

The positive output elementary Luo (POEL) converter is a fourth-order DC–DC having highly non-linear dynamic characteristics. In this paper, new voltage feedback controller proposed to achieve regulation of the POEL converter. contrast state-of-the-art current-mode controllers for high-order boost converters, control strategy uses only state variable purposes. This eliminates need inductor curr...

Concerns about pollution, climate change, limited fossil fuel supplies, and the desire to eliminate energy dependency have sparked a surge in interest electric vehicles (EVs). EV requirements resulted variety of difficulties remedies technology. One them is use DC-DC converters transfer level voltage from battery an other needed levels. An independent converter for each operating might be used ...

In the 2R/R converters imprecision of resistors introduces two types of error. Positive errors introduce a gap in the analog domain, while negative errors cause non-monotonicity in the input/output characteristics. Changing the resistor ratio from 2R/R to 2R/R, with R>R, we intentionally introduce an additional negative error in order to avoid resulting positive error gap. In this paper we prop...
