8c. A buck-boost converter is operating in discontinuous conduction mode (DCM). The inductor value is doubled, but switching frequeney, duty ratio, and average inductor current remain the same. Which mode does the new circuit operate in? Explain your answer. [2pts]

6. A 50 KVA, 2200: 220 V, 60 Hz distribution transformer has a leakage impedance of 0.62 + j 1.02 ohm in the high voltage winding and 0.006 + j 0.01 ohm in the low voltage winding. At rated voltage and frequency, the admittance of the shunt branch accounting for the exciting current is 0.003 - j 0.02 mho when viewed from the low voltage side. Draw the equivalent circuit referred to the high voltage side. (11%)
