Multilevel PWM waveforms can be decomposed into several multilevel PWM components. Phase-shifted carrier (PSC) is an efficient decomposition technique. In this paper, we have first demonstrated the equality of PSC and alternative phase opposition disposition techniques. Second, we have modified PSC to accommodate other disposition techniques. Third, we have investigated the effects of using...

PWM techniques are becoming popular in the present day applications due to the control of amplitude and frequency in the output voltage from VSI. There are two popular approaches for the implementation of PWM Algorithms. Carrier based and Space Vector Approach. Both the approaches give the same performance, but due to simplicity, mostly carrier based approach has been preferred. A large variety...

This paper presents a review of conventional and novel carrier-based PWM methods that are used for control of multilevel inverters. Among the discussed methods are Phase disposition (PD) PWM, Opposite Phase disposition (POD) PWM, Alternative Phase disposition (APOD) PWM, Phase Shifted PWM and Asymmetrical PWM. The paper shows the simulation results and comparison of these methods. Key-Words: Re...

The present studies have examined the effects of mitogens on induction of early response gene expression in normal peripheral blood T and Jurkat cells. Pokeweed mitogen (PWM) or anti-CD3 significantly increases c-jun messenger RNA (mRNA) levels in T cells. This transient PWM-related increase in c-jun transcripts is maximal after 15 to 30 minutes of exposure of T cells to PWM. PWM induces c-jun ...

Commercially available pokeweed mitogen (PWM) has been reported to activate macrophages, leading to production of proinflammatory cytokines and nitric oxide (NO). However, we found that polymyxin B (PMB), a specific inhibitor of endotoxin activity, inhibited the PWM-induced expression of proinflammatory cytokines and NO and the activation of Toll-like receptor 4 (TLR4). A kinetic-turbidimetric ...
