In this paper, a single ended primary-inductor converter (SEPIC) is applied for the speed control of DC Motor using the fuzzy logic controller. The fuzzy logic controller is applied to the closed loop system of the DC motor employing the duty cycle control over wide range of speed. The proposed converter uses a single inductor to allow a continuous-conduction mode by making the current never fall to zero. The proposed converter is controlled using the fuzzy logic controller that operates both in buck and the boost operation; unlike the conventional methods the output is non-inverted. The SEPI Converter used is more applicable for the wide range of voltage applications and as it is independent of the input voltage as the average current through the inductor is same as the load current. The proposed method is simulated using the MATLAB program. An experimental verification is done for a DC motor operated by Fuzzy controlled SEPIC and the results are shown.

A new electronically-controllable fully-uncoupled sinusoidal oscillator, employing four second generation current-controlled conveyors (CCCIIs) and two grounded capacitors, is presented. The oscillation frequency and condition of oscillation are totally uncoupled and electronically adjustable. The circuit has low sensitivities and a high frequency stability factor. SPICE simulation results confirm the validity of the proposed oscillators.

Recently, renewable energies are widely used instead of the fuel energies due to their individual potentials such as its availability, low price and environmentally friendly. One of the most important renewable energies is wind power. As a result, investment in wind power is one of the most interesting research to maximize the profit of the investment and market clearing. In this paper, bi-level optimization technique is proposed to maximize the investment problem and market clearing for the wind power at the same time and in one single problem. Then, karush–kuhn–tucker (KKT) conditions and mathematical programming with equilibrium constraints (MPEC) are applied and tried to find one level optimization problem. Due to the nonlinearity of the optimization equation, the Fortuny-Amat & McCarl (FM) linearization technique is used to linearize the model. Finally, the proposed technique is applied to the IEEE 24 buses. The result proves that the optimization analysis is very easy, fast and accurate due to the linear characteristic of the system. All the simulation results are carried out in MATLAB and GAMS softwares.
