The phenomenon of zero ripple current in an inductor is researched, when two inductors are coupled in only one magnetic core. The condition of zero ripple is discussed, and die principle is explained by the equivalent circuit The e-quivalent reluctance model of the coupled inductors is analysis...
Each slave circuit has its own ripple capacitor Crs, whose voltage mimics the inductor ripple current. A gm amplifier converts the inductor voltage into a current source to charge and discharge Crs. The slave circuit turns on its PWM pulse upon receiving the clock signal, and the current ...
(i.e., approximately constant current demand at the load110) proportionally decreases. Accordingly, the inductor L1may be sized large enough in order to provide a VLoadthat does not fluctuate outside a desired supply voltage range for the load110. However, as previously explained, a conventional...
2.filtering network withcoupled inductorsinstead of a independent inductor is introduced in this article,it s mathematic models and frequency analysis are explained.耦合电感作为变换器设计中的重要部件已经存在很多年了,但其工作机理却没有得到足够的认识。 3.For the gain of the Boost converter,which opera...
FIG. 7 is a graph for comparing a current waveform of the sendust core with that of the ferrite core when a duty is 50%. DETAILED DESCRIPTION OF THE EMBODIMENTS 1. First Embodiment A structure according to a first embodiment of the present disclosure will be explained below in detail with...
The working principle is explained, and a new single-loop direct input current ripple control method for active power ripple decoupling buffer is proposed. Finally, the effectiveness is verified by experimental results.doi:10.1016/j.ijepes.2020.106423Bin Liu...
In the simple shunt capacitor filter circuit explained above, we have concluded that the capacitor will reduce the ripple voltage, but causes the diode current to increase .This large current may damage the diode and will further cause heating problem and decrease the efficiency of the filter. On...
To keep the feedback (FB) net robust from noise, set R2 equal to or lower than 100 kΩ to have at least 6 µA of current in the voltage divider. Lower values of FB resistors achieve better noise immunity, and lower light load efficiency, as explained in the Design Considerations for...
ripple magnitude is approximately 0.14 volts. Based on the measured amount of voltage ripple, the ripple magnitude detector520generates an estimate of the amount of current through the output inductor (i.e., the output current), which, as previously explained, is proportional to the magnitude of...
In this particular case, module M0 is providing virtually all the current to the load while M1 is not outputting current. The topologically inherent power sharing problem can be explained with the output power plane analysis. The output power plane is the graphical representation of the output ...
