Space 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...
