Suppose a three-phase 120V (line-to-line rms) supply is connected to a three-phase full-wave diode rectifier charging the battery. Assume ideal diodes. Var o Voy a Ves o Vde + VBatt Figure 14:Single-phase full-wave rectifier with a battery. Assume that battery voltage is 155V and resistance R is 192 for the following problems. 1. Sketch instantaneous waveforms of de voltage vdc. Include DC and AC voltage peak values. 2. Sketch instantaneous waveforms of A phase current for one cycle. Include peak values and explain your answer. Assume that the charging resistance R is 102. The battery voltage is now unknown. 3. Find the battery voltage if the phase current peak is 7A.
