This paper reports studies on design calculations of inductor and capacitor filter for dc-to-dc buck converter using fuzzy logic. This design takes into account following values. Output voltage = 5 Vdc, Input voltage = 20 Vdc, Operating frequency = 25000Hz, Peak to peak output allowable ripple...
Nevertheless, it can be shown that with the same power dissipation, the dynamic range of an active LC filter can be larger than that of a Gm-C filter. While at present the dynamic range of active LC filters may still not be large enough to meet receivers' requirement, it may be ...
The frequency spectrum supported by 5G and the need to eliminate radio frequency (RF) noise while simultaneously maximizing channel availability presents plenty of headache-inducing problems to even experienced RF filter circuit developers. The high frequencies and demanding system requirements of 5G, ...
It was found that when the load after the LC filter which is widely used in traditional design to filter harmonic of PWM wave has a little change,the output waveform of LC filter has a big change in the research.In order to filter harmonic which is contained in the PWM wave and create...

The dynamic nature of the distribution network challenges the stability and control effectiveness of the microgrids in both grid-connected and autonomous modes. In this paper, linear and nonlinear models of microgrids operating in different modes are presented. Optimal design of LC filter, controller ...
of the system. The power electronic inverters convert solar DC power to AC power before integrating it into the grid. However, the solar power integration to the grid is always affected by the harmonics produced by PV inverters. Passive filters such as the L filter, LC filter, and LCL ...
摘要: This paper presents an optimization strategy for DC-DC converters. The goal is to find the optimum design for the LC output filter in terms of the defined battery voltage and current ripple limits as well as the overall system efficiency (battery and converter)....
