3. A VSI connects a large battery storage system to an ac utility grid. One phase of the circuit is shown in Figure 6.38. The inverter bridge has relative phase angle 8, and is set so its wanted component lags the ac voltage by an angle . For 8 = 45° and = -30°, what is the average power per phase flowing to the ac source? What if = +30°?
