This paper presents a feasible loss model to Buck converter using Matlab/Simulink. The process of energy conversion within the converter leads to power losses. The power loss modeling using small signal model and an algorithm for loss estimation is proposed which ensures fast convergence without the need for any a priori knowledge of the converter loss related parameters. Key-Words: Algorithm, ...

This paper displays an execution of versatile double current mode control (ADCMC) on non-altering buck-support converter. A confirmation of the converter operation with the proposed ADCMC has been performed in consistent state and amid the unsettling influences in the information voltage and the heap resistance and by presenting LC channels. The given recreation with LC channel can give prefera...

This work introduces a new non-isolated buck-boost DC-DC converter. Interleaved configuration of the suggested structure increases the voltage conversion ratio. The voltage rate of the suggested converter can be stepped-up and stepped down for lower values of duty-cycle, which causes to decrease in the conduction losses of the system. The voltage conversion ratio of the recommended structure is...

Standalone photovoltaic system requires a proper battery charge controller. The main disadvantage of photovoltaic system is its variations in output voltage. Therefore to obtain a stable voltage from solar panels, DCDC converters are used. This paper explains the use of cuk converter with MPPT technique in a photovoltaic system. The MPPT is implemented by incremental conductance algorithm with ...

DC-DC converters are widely used as reliable power source for many industrial and military applications, computers and electronic devices. Several control methods were developed for DCDC converters control mostly with asymptotic convergence. Synergetic control (SC) is a proven robust control approach and will be used here in a so called terminal scheme to achieve finite time convergence. Lyapou...

The control of the input voltage of DC-DC converters is frequently required in photovoltaic applications. In this special situation, unlike conventional converters, the output voltage is constant and the input voltage is controlled. This paper deals with the analysis and the control of the buck converter with constant output voltage and variable input.

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 present work deals with the modeling and the stability analysis of the cascaded converters. When a converter tightly regulates its output, it behaves as a constant power load (CPL). The problem of CPLs is that they show negative incremental resistance that causes instability in the system because the control to output transfer function possessed a RHP pole. Hence the CPL has been modeled an...

This paper is concerned with the problem of modeling and simulation of piecewise linear systems with the pulse width modulation control. Models of this kind of systems are widely used in engineering practice, in particular in power electronic converters. The research provides the study of chaos and bifurcations in one of the switching converters – step-down converter under voltage mode control,...
