Can a 500W switch power supply be used for communication base stations?
Conferences > 4th International Confer In order to meet the high power and high stability requirements of communication base stations for power supply, this paper designs a dedicated 500W switch power supply for communication base stations.
What is a communication enabled power supply?
In a communication enabled power supply, not just the output voltage, but current limit, operating frequency and other vital operating parameters become programmable by a host system during operation. Beyond programming, communication permits remote data logging of the operating conditions of the power supply.
How a power supply can communicate with a digital controller?
The first instance of communication is in the programming, when the knowledge of the power supply designer gets downloaded into the microcontroller or DSP. But communication can be maintained and utilized during the entire lifetime of the power supply. The digital controller can provide the interface between the converter and the external world.
What is a suitable standard bus for power supply applications?
Some of the potential suitable standard buses and their basic characteristics for power supply applications are: SMBus System Management Bus ! I2C like bus (2 wire, bi-directional) ! speed is between 10kb/s and 100kb/s ! limited device addressing
What types of power systems are used in communications infrastructure equipment?
Communications infrastructure equipment employs a variety of power system components. Power factor corrected (PFC) AC/DC power supplies with load sharing and redundancy (N+1) at the front-end feed dense, high efficiency DC/DC modules and point-of-load converters on the back-end.
How does a centrally managed power supply work?
In a centrally managed power supply, start-up, shut-down and sequencing can also be supervised remotely by a higher level supervisory system. All these options and the corresponding computing power on-board can open the door for customization of future power supplies and entire power systems through software.
