Space Vector Modulation Based on Classification Method in Three-Phase Multi-Level Voltage Source Inverters
Pulse Width Modulation (PWM) techniques are commonly used to control the output voltage and current of DC to AC converters. Space Vector Modulation (SVM), of all PWM methods, has attracted attention because of its simplicity and desired properties in digital control of Three-Phase inverters. The main drawback of this PWM technique is 
its complex and time-consuming computations in real-time ...

متن کاملSpace Vector Modulation Techniques for Common mode Voltage Elimination in the Three- level Voltage Source Inverter
AbstractThe low common mode voltage vector modulation technique for the three-level cascaded voltage source inverter is presented in the paper. The large number of available states for multilevel inverters can make implementation vector control strategies complicated. The main characteristic of the proposed modulation technique is its simplicity of implementation due to the fact that any availa...
متن کاملSpace Vector Pulse Width Modulation with Reduced Common Mode Voltage and Current Losses for Six-Phase Induction Motor Drive with Three-Level Inverter
Common-mode voltage (CMV) generated by the inverter causes motor bearing failures in multiphase drives.On the other hand, presence of undesired z-component currents in six-phase induction machine (SPIM) leads to extra current losses and have to be considered in pulse width modulation (PWM) techniques. In this paper, it is shown that the presence of z-component currents and CMV in six phase driv...
متن کاملPerformance Improvement of Single-Phase Transformerless Grid-Connected PV Inverters Regarding Common-Mode Voltage (CMV) and LVRT
The single-phase transformerless grid-connected photovoltaic (PV) systems, mainly the low-power single-phase systems, require high efficiency, small size, lightweight, and low-cost grid-connected inverters. However, problems such as leakage current, the DC current injection and safety issues are incorporated with transformerless grid-connected PV inverters. Besides, the new standards such as Lo...
