Interview with double amputee mountaineer Mark Inglis

Arpita Nath
Mountaineer Mark Inglis, the only double amputee to have scaled the tallest mountain in the world the Everest talks about what has kept the fire to climb burning in him
Lucky to have survived
Mountaineer, winemaker, motivational speaker, cyclist, scientist, philanthropist, paralympic medalist and an author - this is all one man, Mark Inglis.

And did we mention that he is the only double amputee in the world to have climbed Mount Everest ? 29 years ago, when he was 23, ....etc

viva questions on multilevel inverters

Inverter:

The Inverter is an electrical device which converts direct current (DC) to alternate current (AC). The inverter is used for emergency backup power in a home. The inverter is used in some aircraft systems to convert a portion of the aircraft DC power to AC. The AC power is used mainly for electrical devices like lights, radar, radio, motor, and other devices.

Multilevel Inverter:

Now a day s many industrial applications have begun to require high power. Some appliances in the industries howev ....etc

Abstract
Multilevel inverter technology has emerged recently
as a very important alternative in the area of high-power
medium-voltage energy control. This paper presents the most
important topologies like diode-clamped inverter (neutral-point
clamped), capacitor-clamped (flying capacitor), and cascaded
multicell with separate dc sources. Emerging topologies like
asymmetric hybrid cells and soft-switched multilevel inverters are
also discussed. This paper also presents the most relevant control
and modulation methods developed fo ....etc

TO DEVELOP A SPEED CONTROL SYSTEM FOR AC MOTOR USING MULTILEVEL (3,5,7) INVERTERS.



INTRODUCTION

Dc motor have been used during the last century in industries for variable speed control applications because its flux and torque can be controlled easily changing the field and armature current respectively.
Farther four quadrant operation of induction motor was achieved.
Induction motor popularly used in industries due to ruggedness and robustness.
To reduces the harmonics we use the multilevel inverter. ....etc

MULTILEVEL INVERTERS



Main feature

Ability to reduce the voltage stress on each power device due to the utilization of multiple levels on the DC bus
Important when a high DC side voltage is imposed by an application (e.g. traction systems)
Even at low switching frequencies, smaller distortion in the multilevel inverter AC side waveform can be achieved (with stepped modulation technique)
Diode-clamped multilevel inverter (DCMI)
Extension of NPC
Based on concept of using diodes to limit power devices ....etc
