Nowadays, one of the challenges in transport electrification is reduction components' size and weight order to improve power density. This often achieved by designing electrical machines with higher rotational speeds excitation frequencies. In addition, converter needs control machine over a wide speed range given mission profile. Therefore, copper losses can significantly increase due combinat...

In this paper, we propose a PWM (Personal Web Map) which is a personal and small database of interesting Web pages to a user, and develop a method to construct it under the user’s control of multiple Web robots. Though general search engine with large databases like YaHoo, AltaVista, MetaCrawler are valid, it is important that a user constructs a small, personal database of relevant Web pages t...

Any industrial or power sector application requires a pulse width modulation (PWM) inverter. Industrial drives in particular are highly concerned with standards. To satisfy the voltage source inverter (VSI) objects, variety of PWM approaches used, including DC input utilizations, suppression higher and lower order harmonics, as well spreading acoustic noise reduction, among others PWMs. One bet...

The trend to use inverter drives in industry is well established. It is desirable to monitor the condition of the motor/drive combination with the minimum of system intervention and at the same time retaining compatibility with the latest generation of AC PWM vector drives. This paper studies the effect of stator resistance asymmetry on the performance of the motor driven by a latest-generation...

Parallel inverters are often used to meet system power requirements beyond the capacity of the largest single structure. They have also been used to reduce harmonics, reduce PWM switching frequency and increase available output voltage or frequency. The type of parallel structure depends on the construction of the load motor, the most prevalent are dual three phase machines, split-phase machine...

Position weight matrix (PWM) is not only one of the most widely used bioinformatic methods, but also a key component in more advanced computational algorithms (e.g., Gibbs sampler) for characterizing and discovering motifs in nucleotide or amino acid sequences. However, few generally applicable statistical tests are available for evaluating the significance of site patterns, PWM, and PWM scores...

The PWM principle is used to control the output voltage of the three-phase inverters. There are many possible PWM techniques proposed in literature. Among these the space-vector PWM (SVM) method is an advanced PWM method and is possibly the best among all the PWM techniques for variable-frequency drive applications. The classical SVPWM which is used in the direct torque control of induction mot...

Power noise generation for masking power traces is a powerful countermeasure against Simple Analysis (SPA), and it has also been used Differential (DPA) or Correlation (CPA) in the case of cryptographic circuits. This technique makes use consumption generators as basic modules, which are usually based on ring oscillators when implemented FPGAs. These modules can be to generate extract digital s...

This paper presents a novel control approach used in shunt active power filter based on variable structure control combined with Random PWM technique (RVSC) that provides robust, fast, and more favorable performance for active power filter. This control strategy is compared with two other strategies to show the effectiveness of the introduced methods; pulse width modulated proportional-integral...
