I. INTRODUCTION
THE BASIC motivation for the use of multilevel inverters
is the reduction of voltage stress on the switching devices
. A cascaded multilevel inverter is a cost-effective option due
to the series connections of identical H-bridge modules. The use
of phase-shifted multicarrier unipolar pulsewidth modulation
(PWM) reduces the harmonic contents of the voltage delivered
by the cascaded multilevel inverter , operating at a lower
switching frequency because of low switching loss. Applications
such as medium-voltage distribution syste..................[:=> Show Contents <=:]

ons. In diode-clamped multilevel inverters, device voltage sharing is achieved via the clamping diodes, whereas lower dv/dt is achieved with stepped voltage changes. However, the diode clamped multilevel suffers from dc-link capacitor unbalance to balance the dc-link series capacitors, two main balancing approaches have been proposed: 1) the use of auxiliary balancing networks and 2) the manipulation of redundant switch states.

symmetrical multilevel inverter (AMI) with the same number of partial cells per phase. An AMI is not more interesting than a classical three phase inverter. The total harmonic distortion of an AMI is compatible to the recommended IEEE std 519-1992 for all feeding possibilities for a given number of partial cells per phase. In order to exploit the main advantages of an asymmetrical design from a load point of view (generation of a high resolution voltage phasor, reduction of the number of power devices for the same resolution, flexibility for the dc-voltage feeding choice), a new solution is in..................[:=> Show Contents <=:]
