Three-Phase Active Front End Rectifier Using Dsp Tms320F2812

The schematic diagram for a basic three phase Voltage Source Inverter (VSI) is shown in . A Three phase voltage source inverter circuit [] changes DC input voltage to a three phase variable frequency, variable voltage output. The input DC voltage can be from a DC source or rectified AC voltage. A Three phase inverter can be constructed by combining three single phase half bridge inverters. It consists of six power switches with six associated with freewheeling diodes. The switches are opened and closed periodically in the proper sequence to produce the desired output waveform.

The paper presents a selective harmonic elimination technique for three phase voltage source inverter with the RL load. A Three phase Voltage Source Inverter (VSI) changes DC input voltage to a three phase variable frequency variable voltage output. The elimination of specific low-order harmonics from a given voltage/current waveform achieved by Selective Harmonic Elimination (SHE) technique. We unite the inductor filter with the capacitor the ripple aspect will turn out to be more or less autonomous of the load filter. Finally Analysis and comparison of Total Harmonic Distortion (THD) for sinusoidal Pulse Width Modulation (PWM) technique and selective harmonic elimination technique has been done. From the comparison it is very apparent that the Total Harmonic Distortion (THD) for selective harmonic technique is less than that of sinusoidal Pulse Width Modulation (PWM) method.

Three phase voltage source inverter converts the DC into AC which in this is fed to the load (RL). Sinusoidal Pulse Width Modulation (PWM) technique is compared with triangular waveform to produces the pulse wave forms; the achieved results are then given to the switches with the desired frequency. Selective Harmonic Elimination (SHE) technique is generally based on the ideas of opposite harmonic injection (3rd, 5th, 7th and 9th order) and it’s given to three phase voltage source inverter switches.
