In addition, the various embodiments of the current source are combined into an improved terminating set for a two to four-wire telephone transmission facility.doi:US4283604 ACharles W. Chambers Jr.USUS4283604 * 1979年6月4日 1981年8月11日 Tellabs, Inc. Current source circuits with common ...
Our earlier phase common mode choke designs are created with ferrite. A ferrite choke is a passive electric component that is capable of suppressing high frequency in electronic circuits. Our two phase, three phase, and four phase common mode chokes have been designed with a Nanocrystalline core,...
As generally acknowledged, the snubber circuits used in the past are connected in series or in parallel with the switch, which can only reduce the noise when the switch is switched and cannot effectively improve the efficiency. Therefore, the soft switching technology was born to improve the ...
It required multiple supply voltages, all at very low noise. It provided +/- 17V, and every critical amplifier had its own +/- 15V power supply regulators and filtering, built with dozens of tiny 78L15 and 79L15 regulators. This is the only time I have seen this approach used. Anyway...
Further throughput increases are expected to be achieved through the use of different computing architectures such as Graphics Processing Units (GPUs), Field Programmable Gate Arrays (FPGAs), or integrated System on a Chip (SoC) circuits. See Ref. [9] for a recent discussion about the evolution...
The concept of averaging has been used extensively in the modeling of power electronic circuits to overcome their inherent time-variant nature. Among various methods, the PWM switch modeling approach is most widely accepted in the study ... G Zhu - University of Central Florida. 被引量: 5发表...
Converting the energy available in the immediate surroundings to electrical energy is a great alternative to the power supply circuit. But there are some challenges like intermittent availability of the source energy and the need for power filtering and conditioning circuits to provide a steady output...
HSRP, which is unique to Cisco platforms, provides network redundancy for IP networks in a manner that ensures that user traffic immediately and transparently recovers from first-hop failures in network edge devices or access circuits. Two or more routers can act as a single, virtual router if ...

Left unfiltered, this noise presents interference problems in electronics and electrical circuits.How do Common Mode Chokes Work?In normal or differential mode (single choke), current travels on one line in one direction from the source to the load, and in the opposite direction on the return ...
