Model predictive pulse-width modulation (MP-PWM) is applied to hybrid active power filter (HAPF) in this paper. The configuration, control, carried-based PWM (CPWM) and filtering performance of HAPF are described in this paper. To realize the MP-PWM, the discrete-time model of the inverter is presented and a cost function is built. The flow chart of realizing the MPPWM is presented. The PWM is ...

ABSTRACT A voltage source inverter is commonly used to supply a three-phase induction motor with variable frequency and variable voltage for variable speed applications. A suitable pulse width modulation (PWM) technique is employed to obtain the required output voltage in the line side of the inverter. The different methods for PWM generation can be broadly classified into Triangle comparison b...

Poke weed mitogen (PWM), a lectin purified from Phytolacca americana is frequently used as a B cell-specific stimulus to trigger proliferation and immunoglobulin secretion. In the present study we investigated the mechanisms underlying the B cell stimulatory capacity of PWM. Strikingly, we observed that highly purified PWM preparations failed to induce B cell proliferation. By contrast, commerc...

An in vitro cell-mediated immune response to pokeweed mitogen (PWM) is described. Rat lymphocytes were stimulated by PWM, by phytohemagglutinin (PHA), and by concanavalin A (ConA). In the presence of PWM only a fraction of the lymphocytes underwent blastogenesis. This was in contrast to the apparent total blastogenesis obtained in response to PHA or ConA. When blast cells derived from each of t...

Abstract— This paper presents the simulation of three phase five-level modular multilevel cascade inverter based on double-star chopper-cell (DSCC). The multicarrier PWM techniques such as Phase disposition PWM (PDPWM), Phase opposition disposition PWM (PODPWM), Alternate phase opposition disposition PWM (APODPWM), and Phase shift PWM (PSPWM) is employed and a comparative study is done based on...

This paper compares the performance of diode clamped three level inverter based STATCOM with sinusoidal and space vector PWM techniques. Space Vector Pulse Width Modulation (SVPWM) technique is the most advantageous technique than the conventional sinusoidal PWM technique for a multilevel inverter. The space vector pulse width modulation technique is an advanced, computation-intensive PWM metho...

A full-order dynamic model of the pulse-width modulation (PWM) DC-to-DC SEPIC converter in discontinuous conduction mode (DCM) is presented in this paper. The derivation procedure is based on the smallsignal PWM switch model in DCM used in conjunction with a PWM derived SEPIC topology. The small-signal characteristics of the PWM SEPIC converter in DCM obtained in a similar way as the small-sign...

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...
