WebSep 28, 2011 · Abstract: This paper presents a grid connected system. Three phase DC-AC inverters used to convert the regulated DC power to AC power suitable for grid connection. Third harmonic injection PWM (THIPWM) was employed to reduce the total harmonic distortion (THD) and for maximum use of the voltage source. the accurate generation of … Weboperation on the THIPWM three-phase inverter. The inverter was supplied by 200 V DC from the DC-DC converter. The result obtained is shown below. Figure 8(a) shows the THIPWM generation, where the third harmonic, acting as a reference, is compared with the triangular waveform THIPWM which is shown in Figure 8(b). THIPWM is a modified technique for generating modulation signals, and it has a lot of features such as reduction in the losses of commutation, greater modulation index amplitude, higher utilisation of the DC-bus voltage, and reduction in the THD of the waveform of output voltages, compared with the SPWM technique [21 – 27]. michigan swat team
