Instructiоns This is аn оpen bоok аnd open notes exаm. Calculators are allowed but NOT computers. Show all intermediate steps. In all the waveforms clearly show the amplitude, time scale, average values, slopes etc. wherever applicable. Problem 1 (25 points) The circuit below operates in steady-state and in CCM. Calculate Vo corresponding to duty ratio of 0.5. The circuit below operates in steady-state and in CCM. Calculate Vo corresponding to duty ratio of 0.5. (Hint: Draw the waveform of current through CC in ON and OFF intervals, and use it to estimate the inductor current). Problem 2 (25 points) The dc-dc converter shown below operates in DC steady-state. The duty ratio, D is 0.5 and the switching frequency is 200 kHz (Hint: DCM operation). For the given operating conditions, draw the following three waveforms over a complete switching period: , , and Calculate the output power and the value of load resistance, R Calculate the peak VA rating of the switch (defined as the product of the peak voltage rating and the peak current rating) based on the given operating conditions. Problem 3 (25 points) Design the power stage of a suitable DC-DC power converter (i.e., calculate all the parameters required below, and show the complete schematic) for the following specifications. Input voltage: 100 V to 140 V; required output voltage: 200 V regulated; max. load current: 10 AMaximum allowable pk-pk output voltage ripple is 1 V and maximum allowable pk-pk inductor current ripple is 2 A. Use a switching frequency of 200 kHz. L: L value Peak current RMS current C: C based on ideal capacitor Maximum ESR RMS current rating Voltage rating Switch and diode: Voltage rating Peak current rating If the voltage across the output side capacitor needs to be limited to no more than 100 V, how will you change your circuit topology? No need to design any component for this modified topology, just show the circuit schematic. Problem 4 (25 points) In the converter below, both the switches are given the same duty ratio, d. Draw the complete small signal average model of the converter at the operating condition corresponding to D = 0.4. (Hint: each of the two bi-positional switches should be replaced by separate ideal-transformer based small signal average models). Using this model, derive the transfer function The plant transfer function for a unity feedback control system is given asCalculate the phase-boost needed from a k-factor based controller to achieve a bandwidth of 5 kHz and phase margin of 60o.
