Q4 Consider you have to design a convertor to produce an output voltage of 36 V from a 3.3-V input DC source. The output current is 0.1 A. The design of above convertor should be for the output ripple voltage of 2 percent. The effect of ESR should be considered having relation to the capacitor value by as, rc = 10-5/c Design the convertor subject to above mentioned design requirements and justify why a boost convertor will not be a good choice here.
