Conductive liquid flow measurement plays a significant part in the food, chemical, pharmaceuticals industry. The electromagnetic flowmeter is basically and mostly used across the world for stream rate measurement of conductive fluid. But it is bulky in size and costly. In this article, we have proposed an alternative flow rate measurement technique for conductive fluid. The polarization-based flow meter has been developed in which four metallic electrodes are inserted across the measuring pipe—the polarization impedance forms when electrodes, which is metallic, come in contact with a conductive fluid. The terminal polarization impedance changes with the conductive fluid flow variation, and this is used as an estimating parameter. The proposed flow meters possess better sensitivity and linearity. The theoretically and experimentally derived result is reported in this article.

This paper focusses on a hybrid topology for a CHB, where some or the modules are equipped with energy storage systems. In addition to the well-known capabilities of the CHB as a STATCOM, the hybrid topology has new advantages as a grid stabilizer. However, the current ripple on the energy storage systems has negative effects which tends to result in expensive solutions. To overcome this inconvenient, a previously known balance strategy is modified to prevent the ripple without compromising the DC-Link balance. This new control method is demonstrated through simulations.

Early evaluation of the Intellectual Property (IP) was conducted in 2017 with the results published at the IEEE Industrial Electronics Society conference (IECON) [1]. This paper extends the previous work by evaluating the potential feasibility and efficacy of the Pulsed Variable Flow Rate (PVFR) cooling algorithm and the DynaCool simulation software using a real-world Proof-of-Concept (PoC) test systemThe efficacy of PVFR was established against two other VFR cooling algorithms. The results on a 1 KiloWatt (KW) test system showed an average of 44.71% and 42.56% reduction in cooling power consumption without affecting cooling performance on sub-component temperatures. Validity was also established for deploying PVFR for multiple daisy chained components in a single cooling loop. PVFR is ideally suited to applications where cooling systems are over-provisioned for a given thermal load.

Modular Multilevel Converter (MMC) has gained popularity in the last decade since it is a transformer-less multilevel converter topology most commonly used in medium and high voltage power conversion applications. There are several component values as well as control parameters which contribute to the operation of MMC. However, the submodule capacitor which is used for energy storage during AC/DC or DC /AC power conversion is one of the most important components in MMC that has a very big impact on the system performance and contributes to large share of the total weight and volume. Under dimensioning the submodule capacitance causes a high capacitor voltage ripple and deteriorate the system performance and on the other hand over dimensioning the submodule capacitance results in higher system cost and system oversize. It is therefore of great importance to dimension the capacitor optimally.

Data mining techniques have been widely applied to various fields including industrial, business, and governmental applications. Missing data is a common occurrence in a number of real-world databases, which may substantially affect the accuracy of data processing. In this paper, we propose a novel approach for missing data estimation by efficiently exploring inter-sensor correlation. Namely, given multiple sensors for data collection, we attempt to recover the missing data of a few sensors by using the measurement data from other sensors. Towards this goal, we develop an iterative solver for missing data estimation. Our numerical experiments on two industrial datasets demonstrate that the proposed method can reduce the imputation error by up to 7.25× compared to a conventional method in the literature.

Existence of zero sequence voltage induces flow of bearing current, causing motor bearing failure, motor winding insulation breakdown and electromagnetic interference in induction motor drive. A space vector based pulse density modulation scheme to eliminate zero sequence voltage in an induction motor drive is presented in this paper. The scheme operates by switching only those vectors of five level inverter which do not generate zero sequence voltage, resulting in a 300 tilted three level space vector diagram. In the proposed work, sub-hexagon containing the reference vector is mapped to inner three level vector space. The mapped reference vector is vector quantized in the sigma delta modulator to obtain switching vectors of inner three level sub-hexagon. Actual switching vectors are calculated by the process of reverse mapping. Proposed scheme operates efficiently in both linear as well as over-modulation region. The scheme includes additional benefits such as absence of minimum pulse width problem, non requirement of complex duty ratio calculations and better harmonic performance, which pertains to space vector based pulse density modulation. The scheme is experimentally verified with 5 HP dual inverter fed open end winding induction motor drive and the results obtained validates the scheme.

This paper deals with a multiple surface sliding control to regulate the output voltage of boost dc-dc converters. The input voltage and load resistance are considered as disturbances and they are estimated using disturbance observer. The estimate is used in the design of multiple surface sliding control to accomplish a high performance. The proposed control algorithm is an equivalent control approach which can fulfill regulatory and servo requirements. Theoretical analysis is presented to show closed loop behavior of the proposed scheme. The efficacy of the proposed control scheme is assessed by simulation under uncertainties in input voltage and load resistance. The proposed control scheme is compared with an existing disturbance observer based integral sliding mode control and it is shown that the proposed scheme outperforms the existing one.

this paper presents a VF Controller (VFC) for self excited induction generator (SEIG) integrated with PV system at DC link feeding linear/nonlinear load. It uses a capacitor bank to excite itself and provide SEIG with reactive power support. A proposed VF controller is consist of a 4-leg insulated gate bipolar transistor (IGBT)-based current controlled voltage source converter (CC-VSC), dump load (Rd) at its DC bus and a PV system support the frequency of the system by providing active power compensation for improving quality of voltage and current under changing load conditions. Despite changes in consumer load the VFC keeps the generated V and F constant. The CC-VSC with PV system fulfills the requirement of reactive and active power of integrated system. The entire system is designed in MATLAB and its performance is analyzed under different loading conditions.
