For dynamic closed loop control of a multilevel converter with a low switching frequency, natural sampled PWM is the best form of modulation. However previous natural sampled PWM implementations have generally been analog. A digital implementation has advantages, particularly for a multilevel converter. Re-sampled uniform PWM, a modulation technique which approaches the performance of natural P...

MOTIVATION Position weight matrices (PMWs) are simple models commonly used in motif-finding algorithms to identify short functional elements, such as cis-regulatory motifs, on genes. When few experimentally verified motifs are available, estimation of the PWM may be poor. The resultant PWM may not reliably discriminate a true motif from a false one. While experimentally identifying such motifs ...

MOTIVATION AND RESULTS The position weight matrix (PWM) is a popular method to model transcription factor binding sites. A fundamental problem in cis-regulatory analysis is to "count" the occurrences of a PWM in a DNA sequence. We propose a novel probabilistic score to solve this problem of counting PWM occurrences. The proposed score has two important properties: (1) It gives appropriate weigh...

The relationship between space vector modulation and regular-sampled PWM techniques for hard-switching PWM inverters and rectifiers are reexamined in this paper. Space vector modulation with optimized apportioning of null vector time that results in minimum current THD is investigated and is compared with previously known methods. The conventional optimal regular-sampled PWM method and its rela...

In this paper, a method for minimization of Total Harmonic Distortion (THD) is proposed in case of PWM inverter. Inverters are widely used in many applications such as in the UPS and ac motor drives resulting in harmonics production. A phase compensation Resonant Controller (RSC) is proposed for 1-phase pulse width modulation (PWM) inverter using MATLAB simulation. The simulation results are th...
