Unformatted text preview: ¹ »¼ ¸ 10¹ . The output voltage is ¹ ½¾¿ ¸ 24¹ and the switching frequency is À ´Á ¸ 250ÂÃÄ . All elements are ideal, and the converter operates in steady state. (a) What is the duty cycle? (b) Sketch the waveform of the MOSFET draintosource voltage. Label the numerical values of all relevant times and voltages. (c) Find the dc component of the voltage waveform of part (b). (d) Sketch capacitor current, capacitor voltage, and diode current. Fig. 2 4) Assume that the MOSFET of the converter of Fig. 2 is not ideal and has a fixed voltage drop of & ±² during conduction. Derive the ratio between average input and average output voltage for a boost converter. Plot the waveforms for all components for this nonideal boost converter. Assume CCM operation....
