Step-Down/Up (Buck-Boost) DC-DC Converter in CCM im DPwit LI 100H pwm_sont R2 215 100% CE30V Vin 10V ME 11001 0.75 control R1 10m BuckBoost Schach Objective: The objective of this experiment is to observe switching waveforms in a Buck- Boost Converter operating at a fixed duty-ratio and consisting of a near-ideal MOSFET and diode. Exercises: 1. Plot the waveforms during the last 10 switching cycles for i,,Vand v.. 2 Plot the average value of v. 3. Plot i, and measure the peak peak ripple Aj and compare it with Eq. 3-28. 4. Plotic and isod waveform. What is the average of ic. Compare the ic waveform with the ripple in idende 5. Plot the input current waveform and calculate its average. Compare that to the value calculated from Eq. 3-31. & Calculate the inductance value of L, if ai, should be 1/3 of the input current. Verify the results by simulations. 7. Change the output power in this circuit to one-half its original value. Measure the peak-peak ripple Ai, and compare it with that in Exercise 3. Comment on this comparison & Calculate Ros from Eq. 3-45 and verify whether the converter is operating on the boundary of CCM and DCM. 9. Find the conduction losses and approximate switching losses (you can assume it is similar to Online Lab #2). Calculate the efficiency of the converter. 10 Assuming we want to actually build the circuit, find the required current, voltage and other ratings of the switch, diode, inductor and capacitor.
