In [8]‚ an interleaved buck converter using a coupled inductor is discussed. The size of the converter is reduced by replacing normal inductors by coupled inductors. But the main disadvantage of using coupled inductors is the presence of leakage inductance in the coupled inductors which may cause a huge voltage spike during transients. In [9]‚ in order to extend the duty cycle of the interleaved converter two extra

inversely proportional to r. b)Derive and comment on the dependence of the induced voltage in the inductor coil on the (i) frequency and (ii) magnitude of the ac current flowing in the long wire. Verify your answers by using the experimental results obtained. If your results do not show the expected relationships‚ explain why. From the experiment that had been done‚ an AC circuit consisting of an inductor coil is connected to the terminals of an AC current source ∆v. We can also refer to fig. 11 as

Wind Energy System based on Buck-boost Controller Abstract – In this edge most of the countries are facing energy related problem therefore researchers are now try to find such a system which should not create any environment issues. In nature there is various non-conventional resources use for the generation of electricity such as water‚ sunlight‚ geothermal energy. But there is disadvantage of solar energy is that we can’t generate power using solar energy in rainy season and in night time

IEEE 519 [5] in the USA‚ these circuits are increasingly being used in the front-end of electronic equipment. Among the several possible topologies [2]‚ the boost PFC shown in Fig. 1 is most commonly used. The control objectives are to track the inductor current to a rectified Sinusoid (so that the line

Study of passive filter characterization for PCB application Chapter 1: Introduction Project Description Passive filters are relatively simple electronic part that consists with resistors‚ capacitors‚ and inductors. The function of the passive filter is to allow a certain range of frequencies to pass‚ can be used to separate signals‚ passing those of interest‚ and also can reject noise and attenuating the unwanted frequencies. In this project‚ there are three type of passive filters that
