A three phase inverter has a Y-connected load of R = 10ohms and L = 20 mH. The inverter frequency is fo= 60 Hz and the DC input voltage Vdc = 220V. The applied control signal is a 120 deg conduction mode. If the phase angle at the fundamental of the current Theta1 equals 27.86 deg, then the conduction time of the transistor and the conduction time of the diode are respectively equal to: Select one: O a. 6.98ms and 1.29ms O b. None of these O c. 1.29ms and 6.98ms O d. 3.99ms and 0.645ms
