A DC-DC boost converter is supplied with an input voltage V, which varies between 30 and 50 V and supplies the load with a constant output voltage of 100 V by controlling the duty cycle. The power delivered to the load varies between 10 to 30 W. What is the worst operating condition for which the inductor must be dimensioned so that the inverter is always in continuous conduction mode (CCM)? (Hint: Study the diagram below) 1.0 V. - Constant V/-0.25 0.75 V/-0.5 0.5 Discontinuous V-08 0.25 0.25 0.75 1.0 1.25 To max-0.074 Pick one of the alternatives: a) Input voltage of 40 V and delivered power of 30 W. b) Input voltage of 50 V and delivered power of 10 W. c) Input voltage of 30 V and delivered power of 30 W. d) Input voltage of 30 V and delivered power of 10 W e) Input voltage of 50 V and delivered power of 30 W 0.50
