(d) Discuss any advantages or disadvantages the Cuk circuit has over other similar switch mode power supply converters 000 指 D 3 Figure 3: Cuk Converter 11. Discuss the operating principles of a Flyback converter. Clearly state the merits or otherwise of the converter 12. In a Flyback converter, Vin = 48V, Vo - 5V, N1/N2 - 6, and the magnetising inductance Lml - 150uH. This converter is operating in equivalent CCM with a switching frequency fs - 200 kHz and supplying an output load Po = 30W. Assuming this converter to be lossless, calculate the waveforms associated with it 13. Figure 4) and Figure 4 (m) show the centre-tap and bridge type circuits having the same load resistance and transformer tum ratio. The primary of each is connected to 115V. 60 Hz supply a. Find the de voltage in each case. b. PIV for cach case for the same d.c. output of 10.35 V. Assume the diodes to be ideal. 14. Discuss the choice of the double-switched flyback over the single-switched version. 15. For the switching converter shown in Figure 4, assume steady-state operation. Also assume that the components are ideal, the inductor current is always positive and continuous and switching period is Ts. If the voltage Vis as shown, determine: a. The output voltage, input voltage and the duty cycle. b. The inductor value required to maintain a peak-to-peak ripple current of 0.4A if the switching frequency is 100kHz v 15 V SR -45 V Figure 4: Boost converter and inductor voltage over a complete cycle.
