-This paper presents modeling, design and analysis of a bidirectional half-bridge DC/DC converter suitable for power electronic interface between the main energy system and the electric traction drive in hybrid electric vehicles. A solar based renewable energy system is considered as input. A parallel dc-linked multi input converter with a half-bridge bidirectional DC/DC cell topology is chosen...

Various controlling schemes are used in dc-dc converters to control the output voltage, rise time, peak time and settling time of the response. In this paper, fuzzy logic and PID control technique are studied on Buck-Boost converter and the mentioned parameters are analyzed. The model is developed in MATLAB/Simulink.

We propose a fast and precise transient response and frequency characteristics simulation method for switching converters. This method uses a behavioral simulation tool without using a SPICE-like analog simulator. The nonlinear operation of the circuit is considered, and the nonlinear function is realized by defining the nonlinear formula based on the circuit operation and by applying feedback....

In this paper a complete multi input-multi output state-space average model for the KY buck-boost converter is presented. The introduced model includes the most of the regulator’s parameters and uncertainties. In modeling, the load current is assumed to be unknown, and it is assumed that the inductor, capacitor, diode and regulator active switches are non ideal and have a resistance in conducti...

Electricity is one of the basic needs modern human life and already so integrated into everyday life. This understandable given coal's ample resources. Another factor that influences growth coal use plants are designed asa burden because price relatively cheaper. However, existence as fuel for power on decline not renewables. One applications renewable energy potential solar generation technolo...

The main objective of this concept is to examine the operation of fundamental buck-based three-phase singlestage ac–dc full-bridge converters. In this concept, the operation of this fundamental converter is explained and analyzed, and a procedure for the design of its key components is derived and demonstrated with an example and general concluding remarks comparing Buck-Based and Boost Based t...

This paper covers the comparison between four different DC-DC converters for solar power conversion. The are buck converter, buck-boost boost and noninverting converter. An MPPT algorithm is designed to calculate battery voltage, current of PV array, voltage output power. It observed that non-inverting converter finest final circuit design has results 12.2V 0.31A 34V 23mW panel, 21.8mW efficien...

Generally two-stage converters are less efficient for low-voltage systems. Bridge rectifiers are having disadvantage of ripple current generation at load generation. In this paper an efficient ac-dc converter is employed for directly conversion of low rating ac supply to high voltage dc power with high efficiency. PI controller is used for Control technique to have efficient operation, and is h...

the cúk converter, which has voltage buck and boost ability, offers high flexibility as an interface device for solar panels. in addition, current ripple can be more reduced because of two input and output inductors at both sides. this paper presents a new application of current-variable inductors in a cúk converter that reduces the size and capacity of storage elements. because of two inductor...
