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...
متن کاملDesign 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...
متن کاملCascaded Multilevel Inverter for Induction Motor Drive
In this paper presents a symmetrical five level cascaded inverter topology for Induction motor drive. It can continuously works at lower power stage. For this symmetrical circuit, when the number of level is increased, the voltage and power will also get increased. For reducing harmonics the Sinusoidal PWM method is used. The multilevel inverter gives the output to drive the three phase Inducti...
متن کاملHigh Efficient Wireless Charger for Electric Vehicle with Reduced Sensitivity to Misalignment using Multilevel Inverter
Wireless power transfer (WPT) has been found to be a practical replacement for cable power transfer which provides a wide range of applications. This technology offers a remarkable solution for charging electric vehicles (EVs) due to more convenience and increased safety. Moreover dynamic (in-motion) wireless charging offers the possibility of reducing the energy storage requirement on the veh...
متن کاملElectric Motor Drive with Inverter Output Filter
The paper focuses on some aspects of control and estimation in electric drives with inverter output filters. The filters are used in some industrial drives with pulse width modulated (PWM) inverters. They smoothes the motor supply voltage and current so nearly sinusoidal shapes are obtained. The filters can also limit the bearing current and shaft voltages. Because of the voltage drop and phase...
