Only precise industrial applications can benefit from the high-frequency performance of variable-speed drives with low switching losses. A five-phase induction motor (FPIM) is connected to a voltage source inverter (VSI) via $LC$ filter...

The voltage source inverter (VSI) and current voltage source inverter (CSI) are widely used in industrial application. But the traditional VSIs and CSIs have one common problem: can’t boost or buck the voltage come from battery, which make them impossible to be used alone in Hybrid Electric Vehicle (HEV/EV) motor drive application, other issue is the traditional inverter need to add the dead-ba...

Adjustable speed drive system requires variable voltage and frequency supply which is invariably obtained from a three-phase voltage source inverter (VSI). A number of Pulse Width Modulation (PWM) schemes are used to obtain variable voltage and frequency supply from an inverter. The most widely used PWM schemes for a three-phase VSI are carrier-based sinusoidal PWM and space vector PWM (SVPWM)....

In common, all industries depends on electrical converters to fed ac motor drives, however owing to high dv/dt of VSI output voltagesbearing failure, insulation failure of motor windings and problems associated with magnetic attraction interference has become a problem. To beat all these tangles, an LC filter is employed between VSI and Motor. But this LC filter creates some unwanted disturbanc...

Introduction Angiogenesis, the formation and development of new vascular network, is essential to tumor growth. Vascular network surrounding tumor tissues, however, exhibits abnormal functional and structural properties distinct from normal blood vessel. Functional abnormalities include higher permeability and altered blood flow, etc. Tumor vascular permeability can be assessed in vivo by using...

The vertical shear instability (VSI) is a source of hydrodynamic turbulence that can drive vigorous mixing and moderate levels accretion in protoplanetary disks, it could be observable the near future. With high-resolution three-dimensional numerical hydrodynamics simulations, we modeled behavior VSI disks with without embedded planets. We then measured its capabilities by comparing full Reynol...

Among innovations and improvements occurred in the past two decades on the techniques and tools used for statistical process control (SPC), adaptive control charts have shown to substantially improve the statistical and/or economical performances. Variable sampling intervals (VSI) control charts are one of the most applied types of the adaptive control charts and have shown to be faster than tr...

BACKGROUND Postpartum hemorrhage (PPH) represents a serious problem for women and obstetricians. Because of its association with hemorrhagic shock and predisposition to disseminated coagulopathy, it is a leading cause of maternal deaths worldwide. Furthermore, the jeopardy of PPH is rising with the secondary form of PPH occurring between 24 hours and 6 weeks postpartum, when women are already d...

Unbiased interpretation of noisy single molecular motor recordings remains a challenging task. To address this issue, we have developed robust algorithms based on hidden Markov models (HMMs) of motor proteins. The basic algorithm, called variable-stepsize HMM (VS-HMM), was introduced in the previous article. It improves on currently available Markov-model based techniques by allowing for arbitr...

This paper presents an integrated power factor correction (PFC) buck-boost buck converter based voltage source inverter (VSI) fed brushless DC motor (BLDC) drive using a single voltage sensor. The speed is controlled by controlling the DC bus voltage of the VSI. An electronic commutation of the BLDC motor is used which utilizes a fundamental frequency switching (FFS) of VSI which in-turn offers...
