In the present paper an H∞ control design is presented for DC-DC Ćuk converter using its average model. Lyapunov equation is used to derivate the controller and to estimate the L2 gain too. Theoretical result is supported by numerical simulations. Key-Words: H∞ control, PWM, Lyapunov equation, Ćuk converter.

Maximum Power Point Tracking (MPPT) algorithms are used in PV system to maximize the output power. In this paper MPPT algorithm is implemented using Ćuk converter in PV system. The dynamics of photovoltaic system is simulated at different solar irradiance and cell temperature and is validated by using Perturb and Observe (P&O) method in Maximum Power Point Tracking algorithm.

Design details and analysis of the properties of a hysteresis switching controller for the Ćuk converter are provided in this paper. The design is based on a switching control law which minimizes a common Lyapunov function derivative for the converter’s continuous modes of operation. These continuous modes of operation are both marginally stable which causes some particularities in the design p...

In this paper multi-input Cuk- derived buck-boost inverter is presented based on Model Predictive Control (MPC). The control technique applied to multi- input because of the several features such as reduction passive elements compared with two-stage topologies and family impedance inverters Z-source Inverter (ZSI), Quazi Source Inverter(QSI), T-Source (TSI), Y-Source (YSI) .in addition , it sui...

This paper presents the design of an auxiliary power distribution network for an electric vehicle. Efficiency is a key element in the design for any electric vehicle and a 48Vdc distribution network will be used throughout the vehicle. The high efficiency Cuk converter has been selected as the most appropriate topology to supply the various distributed loads. To achieve the best compromise betw...

In this paper proposes the design and implementation of a stage voltage converter for use in feed a group of high brightness LEDs (HBLEDs). The use of this lighting technology has been developed en recent years. Currently, theses LEDs have high competitiveness in the market despite its high cost, due to its high energy efficiency. This objective must be performed by the voltage conversion stage...

Sepic and Ćuk converters working as power factor preregulators (PFP) in discontinuous conduction mode (DCM) present the following desirable characteristics for a PFP: 1) the converter works as a voltage follower (no current loop is needed); 2) theoretical power factor is unity; and 3) the input current ripple is defined at the design stage. Besides, input-output galvanic isolation is easily obt...
