Regular structures in 5CB under the joint action of AC and DC voltages
نویسندگان
چکیده
A nematic liquid crystal with high, positive dielectric anisotropy (5CB) has been studied under the influence of the combined action of a DC and an AC electric field. Broad frequency, voltage and cell thickness ranges were considered. Pattern morphologies were identified; the thresholds and critical wave numbers were measured and analyzed as a function of frequency, DC/AC voltage ratio and thickness. The current-voltage characteristics were simultaneously detected.

Neural Network Implementation of a Three Phase Regulated PWM AC to Dc Convener with Input Unbalance Correction
Under unbalanced supply condition low order harmonics will appear at the input and output terminals of the PWM AC to DC converter. Based on the positive and negative sequence components, an unbalanced transfer matrix in terms of the input phase voltages is derived. An on-line method using a neural network (NN) is used to implement this transfer matrix. It is shown that by using an additional lo...
متن کاملTwo New and Novel Cascaded Multilevel Inverters with Less Number of Components Utilizing Series Submultilevel Inverters
In this paper, two new cascaded inverters are proposed, by using the series connection of new Submultilevel inverters. Each of the proposed Submultilevel inverters consists of three batteries and eight power switches. Four algorithms are presented to determine the voltages of these batteries for each of the proposed structures. In this study the comparison between the proposed structures with c...
متن کاملA New Power Management Approach for PV-Wind-Fuel Cell Hybrid System in Hybrid AC-DC Microgrid Configuration
The hybrid AC-DC microgrid (HMG) architecture has the merits of both DC and AC coupled structures. Microgrids are subject to intermittence when the renewable sources are used. In the HMG, since power fluctuations occur on both subgrids due to varying load and unpredictable power generation from renewable sources, proper voltage and frequency regulation is the critical issue. This article propos...
متن کاملDual Z-Source Network Dual-Input Dual-Output Inverter
This paper presents a modified nine switch inverter with two inputs and two Z-source networks. This inverter has two DC inputs and two AC outputs. Input DC voltages can be boosted to the required level. Amplitude, frequency and phase of AC output voltages can be controlled, independently. The proposed converter can be used in applications with two unregulated DC sources, which require feeding ...
متن کاملModified Internal Fixation Technique for Acromio-Clavicular (AC) joint dislocation: The “Hidden Knot Technique”
Acromioclavicular (AC) joint injuries are common and often seen in contact athletes, resulting from a fall on the shouldertip with adducted arm. This joint is stabilized by both static and dynamic structures including the coracoclavicular (CC)ligament. Most reconstruction techniques focus on CC ligament augmentation as the primary stabilizer of the AC joint.The best surgical technique for some ...
