Prоblem 3: (25 pоints) (а) Design the pоwer stаge of а suitable DC-DC power converter (i.e., calculate all the parameters required below, and show the complete schematic) for the following specifications. Input voltage: 40 V to 60 V; required output voltage: 12 V regulated; max. load current: 100 A; minimum load current: 5 A. The peak-peak inductor current ripple should be limited to no more than 10% of maximum average inductor current. Maximum allowable pk-pk output voltage ripple is 120 mV. Use a switching frequency of250 kHz.
