A Novel Multilevel Inverter Employing Additive and Subtractive Topology

Design and Implementation of a New Switch-Diode based Single Source Multilevel Inverter Topology

Multilevel inverters are a new generation of DC-AC converters at medium and high voltage and power levels. These converters have made great strides in the use of industrial applications compared to conventional two-level inverters due to lower harmonic distortion, filter size, EMI and dv/dt. Besides these merits, some disadvantages can be mentioned such as more power electronics devices and com...

A CASCADED H-BRIDGE AND NOVEL MULTILEVEL INVERTER TOPOLOGY FOR INDUCTION MOTOR DRIVE Ratnakumar*

The poor quality of voltage and current of a conventional inverter fed induction machine is due to the presence of harmonics and hence there is significant level of energy losses. The nine level inverter is used to reduce the harmonics. The inverters with a large number of steps can generate high quality voltage waveforms. The concept of multilevel inverters, introduced about 20 years ago entai...

CHAPTER 3 NOVEL MODULATION TECHNIQUES for MULTILEVEL INVERTER and HYBRID MULTILEVEL INVERTER

Novel Multilevel Inverter Carrier-Based PWM Method

 The advent of the transformerless multilevel inverter topology has brought forth various pulse width modulation (PWM) schemes as a means to control the switching of the active devices in each of the multiple voltage levels in the inverter. An analysis of how existing multilevel carrier-based PWM affects switch utilization for the different levels of a diode-clamped inverter is conducted. Two ...
