Unformatted text preview: . Plot the waveforms of all components under this load condition. 3) Design a buckboost converter to supply a load of 100W at 50V from a 25V source. The output ripple must be no more than 1% with a switching frequency of ¸ ¹º ² 100»¼ . Specifiy inductor size and capacitor size. Sketch the voltage and current waveforms over an entire switching cycle. 4) Analyze the Isolated SEPIC of Fig.1.For analysis, assume the converter operates in CCM. a) Derive expressions for the dc components of the magnetizing current, inductor current, load current, and capacitor voltages. b) Draw the voltage and current waveforms of all of the components and express the maximum voltage and current for transistor and diode current and voltage.
