A rectangular core has fixed permeability μr >> 1, a square cross section of dimension a x a, and has centerline dimensions around its perimeter of b and d. Coils 1 and 2, having turn numbers N1 and N2, are wound on the core. Consider a selected core cross-sectional plane as lying within the xy plane, such that the surface is defined by 0 < x < a, 0< y< a. (a) With current I1 in coil 1, use Ampere's circular law to find the magnetic flux density as a function of position over the core cross-section. (b) Integrate your result of part (a) to determine the total magnetic flux within the core. (c) Find the self-inductance of coil 1. (d) Find the mutual inductance between coils 1 and 2.
Can A Buck Converter with Synchronous rectifier operate in DCM at a light load If the load is disconnected how does this affect the Inductor current
Design a buck converter that has an output of 12 V from an input of 18 V. The output power is 10 W. The output voltage ripple must be no more than 100 mV p-p. Specify the duty ratio, switching frequency, and inductor and capacitor values.
given analog signal : x(t)=8cos(6,000pi)+5cos(14,000pit) t>=0 sampled at rate 12,000 Hz a) sketch the spectorum of the orignal signal and the sampled signal from 0 KHz and 25 KHz.
Reduce the equation to the slope-intercept form and give the slope and the y-intercept.
An RL circuit consists of a switch, an emf source Eo, a 4 k-ohm resistor, and a 3 H inductor. If the potential across the resistor is 96 V 6 ms after the switch is closed, find the source emf, Eo.
Discuss why it is important to understand how interpret data from op amp datasheets. How might this skill be used when designing op amp circuits.
A very long insulating cylinder of charge of radius 2.30 cm carries a uniform linear density of 17.0 nC/m . If you put one probe of a voltmeter at the surface, how far from the surface must the other probe be placed so that the voltmeter reads 180..
