How does the discontinuous transition point change if switching frequency is increased in a buck converter?...
In the following buck converter, let the switching frequency be 50 kHz. Determine if the converter is in CCM or DCM Compute the average inductor current, peak-peak current ripple Average transistor current, average diode current Peak current in the transistor Peak-peak ripple in the output voltage f.Power delivered by the input 12V source Vd=12 ,Vo=8V ,R=4ohm, L=20uH ,C=50uF
ins (a) Fig. 3 3.For the buck converter of Fig. 3, V.-24V, L=2000H, R-2002, the switching frequency, f.-10kHz, and D 0.4 and it is operating in discontinuous conduction mode (DCM). (Assume ideal components) (a) Determine the output voltage. (10pts) Next (b) Determine the discontinuous conduction time over the one switching period (15pts) Next (c) Draw the inductor current waveform in detail at least over the one switching period. (15 pts) Next

Are there any ways to reduce the switching loss of the MOSFET in a Buck Converter? Please list and explain all of the possible ways to do this. Thank you!
Why does varying input frequency to a buck converter affect the magnitude of the output voltage ripples?
Q4. (a) Fig. Q4(a) shows a buck-boost converter. Sketch waveforms for the choke current when in both the continuous conduction mode (CCM) and thre discontinuous conduction mode (DCM). If data are: switching frequency 100kHz L1 20yH calculate the average choke current at which the converter transitions from thre CCM to the DCM D1 Vin out 0V Fig. Q4 (a) 8 marks (b) The diode D1 in Fig. Q4(a) is depicted as a p-n type. Give reasons why a 2 mark...

Please help in this question conserning the buck-boost
converter
4. a. Draw a buck-boost converter to be implemented with an IGBT and diode b. Suggest suitable component values if such a converter is to serve resistive loads between 15 W and 30 W with a constant 8 V output, when the converter's input can vary between 5 V and 12 V. The output peak-to-peak voltage ripple should be less than 5% of the output voltage. The converter should operate in...
