A dc converter is a lossless dc transformer that must supply regulated outputted voltage under varying load and input voltage condition. Also the converter values changes with time, temperature and pressure. Hence to control the output voltage, detailed understanding of the dynamic behaviour, transient response and small signal characteristics of the converter is required, which can’t be unders...

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...

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...
