Switched reluctance machines (SRMs) have received increasing attention for their many potential uses, such as wind power and electric vehicle (EV) drive systems. The Quasi-Z-source Integrated Multiport Converter (QZIMPC) was recently introduced to improve the reliability of SRM driver through small capacitance values. It is not possible, however, simultaneously energize deenergize two phases in...

Well-characterized certified reference materials are needed by laboratories in the food testing, dietary supplement, and nutrition communities to facilitate compliance with labeling laws and improve the accuracy of information provided on product labels, so that consumers can make good choices. As a result of the enactment of the Nutrition Labeling and Education Act of 1990 and the Infant Formu...

In 2014, the Nobel Prize in Chemistry was awarded to three scientists who have made groundbreaking contributions to the field of superresolution (SR) microscopy (SRM). The first commercial SR microscope came to market a decade earlier, and many other commercial options have followed. As commercialization has lowered the barrier to using SRM and the awarding of the Nobel Prize has drawn attentio...

Piezoelectric amplifier is a very important part of the piezoelectric actuator. It does not only require high positioning accuracy, but also high frequency response. This paper designs the error amplifier drive power consisting of high-voltage op amp and discrete components, consisting of an error-amplified circuit, a power amplifier circuit, a feedback network and a discharge circuit. A compen...

This paper presents a simulation model for a large chipper drive used in a paper mill. If the chipper drive is a slip ring induction motor, several advantages arise from using a rheostat in the rotor circuit. This paper will investigate the impact of a rotor circuit rheostat with respect to starting behavior and heavy duty load impulses. The chipper drive is modeled in Modelica, an object orien...

Today, Switched Reluctance Motors (SRM) are widely used in research and daily life due to their ability provide large starting torque low manufacturing costs. In terms of kinematics control, the SRM drive system displays high nonlinearity motor structure inverter, which switches between phases operate motor. Most current focuses on controlling without considering caused by inverter. A few studi...

Since the magnetizing characteristics are highly non-linear in nature, the torque ripple is high in the Switched Reluctance Motor (SRM). The torque ripple can be minimized by using a novel control technique called Direct Torque Control (DTC). In DTC technique, torque is controlled directly through control of magnitude of the flux-linkage and change in speed of the stator flux vector. The flux a...

An adaptive online flux-linkage estimation method for the sensorless control of switched reluctance motor (SRM) drive is presented in this paper. Sensorless operation is achieved through a binary observer based algorithm. In order to avoid using the look up tables of motor characteristics, which makes the system, depends on motor parameters, an adaptive identification algorithm is used to estim...

Switched reluctance drive (SRD) system has been used in many applications. However, because of its inherent nonlinearity, the design and analysis of SRD system is relatively difficult. In this paper, the development of design and analysis tool for SRD system based on MATLAB/GUIDE is studied. Firstly, the steps for the development of graphical user interface (GUI) by MATLAB/GUIDE are summarized....
