A flyback converter is to be designed so that it operates in continuous "current" (flux) mode with a duty cycle of D = 0.45 when input voltage Vs = 48 V, output voltage Vo = 30 V, switching frequency fs = 25 kHz, and load resistor R = 15 W. Determine the necessary transformer turns ratio and transformer magnetizing inductance that will make the minimum inductor current to be 25% of the average. Confirm your answer with PSIM.
Q. Consider the circuit of Figure with V S = 94 V, V Z = 12 V, R = 820 , R L = 220 , R S = 0, and R Z = 25 . Assume the reverse saturation current of the zener diode to be
what is the effect of back emf ?
If the instruments has no drift it is perfectly reproducible. No drift means that with a given input the measured values do not vary with time. Drift may be classified into thre
PNP The other kind of BJT is the PNP with the letters "P" and "N" standing for the majority charge carriers inside the dissimilar regions of the transistor. Figure:
Q. What is meant by regulation? The output of most power supplies should be a constant voltage. Unfortunately, this is difficult to achieve. There are two factors that can caus
Give the properties and application of brass. Brass - It is an alloy of copper and zinc with 60 percent copper and 40 percent zinc. Its electrical resistivity of Brass is 7.0
Both GSM and DECT use GMSK, but with different Gaussian filters (BGT = 0.3 in GSM, BGT = 0.5 in DECT). What are the advantages of having a larger bandwidth time product? Why is the
