In the existing high speed, highly advanced technology of IC designs, the need of efficient pattern generator to minimize the test power dissipation without affecting the overall system performance. Built in Self Test (BIST) is promising DFT technique and the extremely important module. The most widely implemented pattern generator used in BIST is Linear Feedback Shift Register (LFSR) because of its...
Sags are the foremost power quality problem encountered by industrial consumers since they frequently causes the interruption of manufacturing processes that can result in significant economic loss. To resolve such problems, a voltage sag compensator is often installed by industrial consumers within critical industrial applications. However, the operation of the compensator takes a few milliseconds...
Numerous industrial facilities involve the installation of load transformers with their respective loads. As loads are turned on and off, these transformers are energized and de-energized, respectively, which can cause serious disturbances to sensitive loads. An inrush current, which typically occurs when a transformer is energized, can easily be observed using on-line uninterruptible power supply...
A 3D electromagnetic time domain model of a particle accelerator cavity was generated for the measurements of beam position using a patch antenna and (for comparison) a pickup by applying a signal at 3GHz. The variations in position from the central axis were modelled using CST Microwave Studio. The results demonstrated that the model can be applied to accelerator beam position monitoring for optimization...
Many industrial applications involve loads which are very sensitive to electrical disturbances in the supply. These instances involve both various types of voltage unbalance as well as more series disturbances such as symmetrical and asymmetrical faults. This paper proposes a voltage unbalance and an unsymmetrical fault correction technique for a three phase load utilizing an industry-standard current...
Most industrial facilities involve use of various types of auxiliary loads in addition to a main sensitive load. Each of these loads are generally accompanied by load transformers. As these auxiliary loads are switched-in, their transformers also become energized. An inrush current often develops when the transformer is switched-in. This paper proposes an inrush current elimination technique for line-interactive...
Numerous sensitive loads of commercial, industrial and domestic use depend upon an uninterruptible power supply (UPS) system to ensure uninterrupted, reliable, and high quality power during outages as well as over voltage and under voltage conditions to maintain healthy operation. In case of a power failure or other disturbance, a UPS system generally takes over the load within a few milliseconds...
