Nine Level Inverter
A new scheme for nine-level voltage space-vector generation for medium-voltage induction motor (IM) drives with open-end stator winding is presented in this paper. The proposed nine-level power converter topology consists of two conventional three-phase two-level voltage source inverters powered by isolated dc sources and six floating-capacitor-connected H-bridges. The H-bridge capacitor voltages are effectively maintained at the required asymmetrical levels by employing a space vector modulation (SVPWM) based control strat ....etc

ABSTRACT

A new operational mode for diode-clamped multilevel inverters termed quasi two-level operation is proposed. Such operation aims to avoid the imbalance problem of the dc-link capacitors for multilevel inverters with more than three levels and reduces the dc-link capacitance without introducing any significant voltage ripple at the dc-link nodes. The proposed operation can be generalized for any number of levels. The validity of the proposed multilevel inverter operational mode is confirmed by ....etc

Diode Clamped Multilevel Inverter Fed Induction Motor


INTRODUCTION

Two level voltage source inverters produce an output voltage or a current with levels either 0 or Vdc

In high power and high voltage application these two level inverters, however, have some limitations in operating at high frequency mainly due to switching losses and constraints of device ratings.

Unique structure of ML-VSIs allow them to reach high voltages with low-harmonics without use of transformers ....etc

irony in nine ten by warren leight

Warren Leight s Nine Ten is a play that could only be a play. Its ensemble focus and emphasis on character interactions unfolding in apparent real time are essential to its theme and these are two effects that can be created with far more strength and certainty in performance than on the page.

The play portrays five people who have been summoned for jury duty and are waiting for their names to be called. They are split into two Warren-Leightgroups. First we are introduced to John, a dull bond trader, and ....etc
