Consider the three-phase inverter circuit of Fig.1 with R-L load and Y-connected source with R=2.0?,L=10mH, inverter frequency of f0?=47.619Hz, dc input voltage of VS?=313.97V,vTH,A?(t)=105.73sin(?0?t?12.36?),vTH,B?(t)=105.73sin(?0?t?132.36?), and vTH,C?(t)=105.73sin(?0?t?252.36?). The inverter uses 180 -degree conduction control (see Fig. 6.6 of course textbook pp. 297). Any transistor may be used in place of the MOSFETs; all six must be identical. 1. Theoretical Background (a) (i) Determine vAn1 ? by means of Fourier analysis of the vAn ? waveform. (ii) Using the results of 1(a)(i), obtain the ripple component vripple ? waveform in the output voltage. (iii) Obtain iA1? by means of Fourier analysis of the iA? waveform. (iv) Using the results of 1(a)(iii), obtain the ripple component iripple ? waveform in the output voltage.
