Power battery test equipment is widely used to produce and new energy vehicles storage containers. To address the problem of DC bus voltage fluctuations that affect accuracy output current, a high-accuracy control strategy based on nonlinear extended state observation (NLESO) terminal silding mode controller (TSMC) load current estimation. Simulation experimental results show has good suppressi...

Now-a-days, the systems are coming with the high speed processors. With the development in the processors, the CPU performance is increasing day-by-day and making applications such as data mining, data warehousing, and e-business commonplace. This growth in computational power requires that the I/O subsystem should be able to deliver the data needed by the processor subsystem at the rate at whi...

The main objective of this project to control the common mode leakage current by using virtual dc bus with PV systems. The power which we receive form the PV panel is not a constant supply due to various condition. In order to overcome this issue we are using Buck Boost converter for generating constant voltage supply to the inverter. The negative pole of the dc bus is connected directly to the...

The penetration of renewable energy in modern power system, microgrid has become a popular application worldwide. In this paper bidirectional converters for AC and DC hybrid microgrid application are proposed as an efficient interface. To reach the goal of bidirectional power conversion, both rectifier and inverter modes are analyzed. In order to achieve high performance operation and single-ph...

Phasor measurement unit s (PMUs) provide globally synchronized measurements of voltage and current phasors in real-time and at a high sampling rate. Hence, they permit improving the state estimation performance in power systems. In this paper we propose a novel method for optimal PMU placement in a power system suffering from random component outages (RCOs). In the proposed method, for a given ...

In this work, we address the problem of online travel time prediction in the context of a bus journey. That is, a journey may be ongoing in the sense that journey events already indicated the progress of the bus on its route. For such an ongoing journey, we are interested in the current prediction of the traveling time from the current bus stop to some destination via a particular sequence of s...

Background: Persistent thyroglossal duct leads to a fibrous cyst formation named thyroglossal cyst which is the most common form of congenital cyst and usually located in the midline neck below the hyoid bone. Rarely the thyroglossal cyst is associated with thyroid cancer. Although the Sistrunk procedure is often considered adequate, currently there is no clear consensus on the optimal manageme...

The firing angle control of thyristor full wave ac-dc converters to set the desired DC bus voltage in Uninterruptible Power Supply (UPS) systems have drawbacks of pulsating input current, high harmonic content, low pf, low efficiency and large size of inductors and filters. International standards impose several constraints concerning the electric power quality and harmonic content of the line ...
