This paper proposes a simple way to design proportional integral derivative (PID) controller for DC-DC buck converter. work concerns getting the formula calculate Kp, Ki, and Kd parameters from PID easily. The main advantage of this is that tuning process K<sub>P</sub>, K<sub>I</sub> K<sub>D</sub> will be simplified just by entering R, L, C component values c...

1 This work is supported by Philips Research, Briarcliff Manor, NY, through Colorado Power Electronics Center Abstract – Single-switch step-up/step-down converters, such as the buck-boost, SEPIC and Cuk, have relatively high voltage and current stresses on components compared to the buck or the boost converter. A buck-boost converter with two independently controlled switches can work as a boos...

Chauhan, Shweta. M.S.Egr, Department of Electrical Engineering, Wright State University, 2014. Hysteretic controlled DC-DC converters. Switched-mode DC-DC converters are widely used in applications requiring stepup and step-down of DC voltages or currents. These converters find their use in portable applications such as laptops and smart phones, radio-frequency power amplifiers, as light emitti...

Due to the nonlinear and nonminimum phase characteristics of buck-boost converter, design its controller has always been a challenging problem. In this paper, multi-index feedback linearization control strategy is proposed converter. Firstly, by constructing an appropriate output function, original system mapped into combination linear subsystem subsystem. Then, according structural these two s...

A digital control algorithm for a current-mode (CM) and a voltage-mode (VM) synchronous buck converter (SBC) is developed. In both cases, the design leads to a stable controller, even for a duty cycle larger than 50%. The desired output voltage and the transient response can be independently specified. Moreover, zero steady-state error in the output voltage can be obtained with the aid of addit...

– A buck converter controlled by naturally-sampled constant frequency pulsewidth modulation in continuous mode of operation is analysed. For a fixed set of converter parameters and varying the dc supply voltage only the buck converter can be driven into chaos through a process of period doublings. A good agreement between simulation and experiments is obtained. Key-words: buck converter , ident...

Due to scarcity of fossil fuel and increasing demand of power supply, we are forced to utilize the renewable energy resources. Considering easy availability and vast potential, world has turned to solar photovoltaic energy to meet out its ever increasing energy demand. The mathematical modelling and simulation of the photovoltaic system is implemented in the MATLAB/Simulink environment and the ...

In this paper, a two-surfaces sliding mode controller (TSSMC) is proposed for the voltage tracking control of a two input DC-DC converter in application of electric vehicles (EVs). The imperialist competitive algorithm (ICA) is used for tuning TSSMC parameters. The proposed controller significantly improves the transient response and disturbance rejection of the two input converters while p...

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...

This paper presents the design and analysis of a high efficiency, PWM (Pulse-Width-Modulation) Buck converters for mobile phone applications. The steady-state and average-value models for the proposed converter are developed and simulated. A practical design approach which aims at systematizing the procedure for the selection of the control parameters is introduced. The switching losses are red...
