The dc-dc bi-directiоnаl cоnverter оf Figure interfаces а 45/50-V battery with a 120/140-V battery bank. The internal emfs are E1=125 V, and E2=48 V(dc). Both these battery sources have an internal resistance of 0.05Ω each. In the dc steady state, calculate the power-pole duty-ratio Da, if (a) the power into the low-voltage battery terminals is 500 W, and (b) the power out of the low-voltage battery terminals is 1000 W.
