The Difference Between ac and dc Plugs and Power Connectors
2021年4月30日 · Although product designers can choose any connector for the dc power plug, many electronic products use USB input power jacks to receive 5 Vdc. Because of this common practice, it is prudent to use USB plugs only on power supplies with a 5 Vdc output voltage rating to not damage the many products using USB power jacks that are expecting 5 V ...
The Difference Between Input and Output Adapter Plugs - ASME
2022年3月23日 · The plugs and jacks available for the transfer of dc power from the power supply to the load afford the designer many more choices and fewer standards than the ac input power. Care should be taken to ensure that the dc connectors have the proper voltage and current rating for the application.
The Basics of USB-C and USB Power Delivery - ASME
2021年3月30日 · USB Power Delivery's advantage to create a single power source that can be used to provide power for multiple products will be of greatest benefit when the products are sophisticated and expensive. An example of an application for USB Power Delivery is a power source that is used to charge cell phones, laptops, tablets, smartwatches, and earbuds.
Dc-Dc Converters for Photovoltaic Renewable Energy Systems
2021年11月23日 · In contrast to the 1000 Vdc photovoltaic systems, by increasing panel numbers in strings to deliver 1500 Vdc to the combiners for the same 15 MW of power outlined on the previous slide, current drops to 66.6 percent of the 1000 Vdc value and resistive cable losses to 44.4 percent because of the "I2" in I2R, resulting in higher system efficiency and lower cost of …
Harvesting the Power of the Ocean - The American Society of …
2019年3月29日 · At the shore substation, the dc power could be inverted to ac, and connected to the grid. The buoys would be placed in water depths of 100 to 200 feet—before the waves start to break and dissipate their energy—at about one to three miles offshore, from where the parks would be virtually imperceptible from the beach.
Five Key Trends in Industrial Connectivity - ASME
2020年9月9日 · There are many promising areas, like connectivity for DC power transmission and E-Mobility. But none is coming into focus faster than Single Pair Ethernet (SPE). SPE is a complete eco-system of miniaturized networking componentry for delivering high-speed data for Industry 4.0/IIoT.
Design Protocols Via IEC 61558 for Power Supplies - ASME
2021年8月11日 · The source frequency can be up to 500 Hz. Output power ratings are typically up to 25 kVA for single-phase transformers or linear power supplies (40 kVA for 3-phase) and up to 1 kVA for single-phase or 3-phase switch mode power supplies. IEC 61558 comprises two parts: 61558-1 contains general specifications
Learn Design Considerations for Ac-Dc Power Supplies - ASME
2021年10月20日 · The environment a power supply operates in will affect the selection of an ac-dc power supply. Most power supply operating temperature specifications include derating factors for extreme cold and hot temperatures. Cold temperature power derating is often due to the temperature coefficient of capacitors used in the design of the supplies.
B31.1 - Power Piping - ASME
ASME has been defining piping safety since 1922. ASME B31.1 prescribes minimum requirements for the design, materials, fabrication, erection, test, examination, inspection, operation, and maintenance of piping systems typically found in electric power generating stations, industrial and institutional plants, geothermal heating systems, and central and district …
Connecting Power Supplies for Increased Power Output - ASME
2021年9月15日 · When providing combined power, care must be taken to ensure power is delivered in a balanced manner by all of the supplies. Power Supplies Connected for Redundancy Redundant power supplies are a topology where the outputs of multiple power supplies are connected to increase the system’s reliability but not to increase the power output.
