Prоblem 3: (25 pоints) Design а switch mоde dc-dc converter to meet the following specificаtions. Use а switching frequency of 200 kHz. Input voltage: 40V to 60V Output voltage: 120V Maximum load current: 10A Maximum output voltage ripple: 0.6 V pk-pk Maximum input current ripple 2 A pk-pk The converter manufacturer has a large stock of 470uF/150V capacitors each of which has an ESR of 0.1 ohms, and RMS current rating of 2 A. You are required to use only this capacitor at the output; however, you may connect as many of these capacitors as needed in parallel. Note that when you connect n capacitors in parallel, the effective C becomes n C, the effective ESR becomes ESR / n and the effective RMS current rating becomes n x RMS current rating. Draw the complete schematic and provide all the relevant design details for each of the components (including inductors, capacitors, switches and diodes) in the schematic. If you connect capacitors in parallel indicate how many capacitors are in parallel.
