A dc-dc converter for a computer notebook is to be designed based on design specifications shown in the picture. Complete the design by specifying the type of dc-dc converter to be employed as well as the size (or value) of inductor and capacitor to be used. Use minimum inductor size (or value) for your design.

In the common mode, ..... ..... ..... Select one: a. the output signal are in-phase b. an identical signal appears on both the inputs c. the outputs are connected together d. both inputs are grounded

a. b. C. There is a dc-dc converter that provides isolation between input and output current. Identify the converter type and describe the operation. Draw the equivalent circuit to support the explanation. Assume the converter operates in continuous-current mode. Explain why a switched -mode dc-dc converter is better that a linear regulator. As an electrical engineer, you are required to design a chopper circuit with an output voltage of 10 V from a 30 V input with switching frequency of 50 kHz. The circuit is operated in continuous current, and output ripple voltage is less than 0.8% with resistance load of 30 Q. Assume the inductor value is 50 % larger than Lmin and assume ideal components for this design. Identify the chopper type and construct the circuit with IGBT as the power switching.

A step down converter has a load resistance R-0.50hms. an input voltage Vs-200V and a battery voltage E-20V. The average load current la=250A and the converter frequency is 400 Hz.
