Passive Pfc for Flyback Convertors
A new passive Power Factor Corrector (PFC) based on Valley Fill (VF) is proposed for an off-line Flyback converter. By adding an extra winding which is magnetically coupled to the Flyback transformer and electrically coupled to the VF, higher Power Factor (PF) and lower Total Harmonic Distortion (THD) can be achieved. The proposed circuit uses a high frequency inductor, low voltage capacitors t...
متن کاملDirect Frequency Information Processing Using Neural Networks
Frequency information processing using complex valued neural networks is proposed Learning process is realized by adjusting delay time and conductance of neural connections Experimental results demonstrate that the network learns successfully an intended output pro le smoothly in frequency domain This result is applicable not only to frequency signal processing but also to future optical neural...
متن کاملThyristors and Triacs Control Gate Trigger Circuits
The thyristor is a power semiconductor device with the control terminal called grid or gate (G). The device name comes from the similarity of operation with the gas triode: thiratron transistor. Because the thyristors are mainly used in the controlled rectifier structures, the technical literature calls them as SCR (Semiconductor Controlled Rectifiers) devices. After the series manufacture star...
متن کاملMetastability in Latches, Arbiters and Data-convertors
Real-time digital systems and asynchronous computer systems have an inherent risk of occasional failures due to metastability in various components used to control data-transfers. This possibility has been known for a long time, although it is sometimes forgotten or overlooked. There is renewed interest in asynchronous computer systems because of the prospects they offer for lower power operati...
متن کاملDirect Digital Frequency Synthesis Using a Modified Cordic
This paper introduces a new approach to direct digital frequency synthesis (DDFS) based on the Coordinate Rotation (CORDIC) algorithm. The modifications to the standard CORDIC algorithm introduced in this paper allow fine frequency resolution, and exhibit significant potential for low power applications. The new architecture does not need a large ROM and can be implemented on a general purpose ...
