Calculate the maximum power that you obtain from this converter for the minimum and maximum specified output voltages. For each case: find the duty ratio, efficiency (assume no losses in the switches), input power, power dissipated in the inductor’s ESR, and equivalent load resistance.

Explanation:

2. (20 pts) For a switching frequency of 100 kHz, calculate the inductor value required to limit the pole ripple current to 100 mA when the load voltage is 4.5V and 18V. Which inductor will guarantee a ripple of 100 mA (or less) for the entire specified range of load voltage? 3. (60 pts) Assume that L, C, and the switching frequency are large enough so that the throw voltage and pole current have infinite stiffness. Consider the circuit to be operating under conditions where the inductor's maximum current is 6A and assume that the inductor's ESR is 0.1Ω. Draw the equivalent circuit to analyze dc steady state operation. Calculate the maximum power that you obtain from this converter for the minimum and maximum specified output voltages. For each case: find the duty ratio, efficiency (assume no losses in the switches), input power, power dissipated in the inductor's ESR, and equivalent load resistance. (hint: you can use the principle of power balance combined with Kirchoffs current aw to find an expression for the equivalent duty ratio) Just question 2 and 3

1. (20 pts) Sketch a schematic of this converter using a SPDT switch (no semiconductors) and appropriate voltage and current stiffeners (inductors and capacitors). Label the pole voltage, throw voltage, pole current, input current, and output current on your schematic. Indicate the polarity of your throw voltage and pole current. Redraw your schematic using a MOSFET and diode combination. What type of de-dc converter is this? 2.
