Selective Harmonic Elimination (SHE) for 3-Phase Voltage Source Inverter (VSI)
نویسندگان
چکیده
The simple Selective Harmonic Elimination (SHE) for 3-Phase Voltage Source Inverter (VSI) is presented here. The proposed work is to examine the Selective Harmonic Elimination (SHE) and to eliminate harmonics produced by Pulse Width Modulation (PWM) inverter. The selective harmonic elimination method for three phase Voltage Source Inverter (VSI) is generally based on ideas of opposite harmonic injection. In this proposed scheme, the lower order harmonics (3rd, 5th, 7th, and 9th) are eliminated by the dominant harmonics of same order generated in opposite phase by Sinusoidal Pulse Width Modulation (SPWM) inverter, The elimination of precise low-order harmonics from a given voltage/current waveform is accomplished by Selective Harmonic Elimination (SHE) technique and by using this scheme the Total Harmonic Distortion (THD) created has been reduced which is more effective. Analysis of Sinusoidal Pulse Width Modulation (SPWM) technique and Selective Harmonic Elimination (SHE) is simulated using MATLAB/SIMULINK model.
