CONTROL OF THREE PHASE FOUR WIRE ASYMMETRICAL FIFTEEN LEVEL INVERTER USING HYBRID BI-TRI DIMENSIONAL SPACE VECTOR PULSE WIDTH MODULATION
K ESWARAMOORTHY V K SHUNMUGHANAATHAN
In general the tri-dimensional space vector pulse width modulation has been widely used for control of three phase four wire system converters. In this paper, the output voltage of inverter has been generated by the grouping of two different control schemes. One is for abc coordinate-based reference voltage generation for proposed inverter half-bridge circuit, and other is equivalent reference voltage of abc in αβ0 coordinate for proposed inverter full bridge circuit. A simple bi-dimensional scheme calculated the generated gating signal of reference voltage vector location. The proposed scheme is verified by MATLAB/Simulink .
