Description

智能电源及其智能供电的方法Intelligent power supply and its intelligent power supply method 技术领域Technical field
本发明涉及通信领域的智能供电技术，尤其涉及一种智能电源及其智能供电的方法。The invention relates to an intelligent power supply technology in the field of communication, in particular to an intelligent power source and a method thereof for intelligent power supply.
背景技术Background technique
目前在通讯电子、信息(IT，InformaTion)服务器等很多设备的电路板设计中都离不开电源，并且是功率大，电压种类多。按照目前的常用的是分为独立电源模块与板上电源两种，对于板上电源的分布比较零散，电压种类、电流大小、上电时序等各不相同，设计时比较复杂。At present, in the circuit board design of many devices such as communication electronics and information (IT, InformaTion) servers, the power supply is indispensable, and the power is large and the voltage types are large. According to the current common use, it is divided into two independent power modules and on-board power supplies. The distribution of power on the board is relatively scattered, and the voltage type, current magnitude, power-on sequence, etc. are different, and the design is complicated.
板上电源设计是基于所使用的芯片，所用的芯片的电源需求都是在数据手册中标出的，大致分为两种，AVS电源和固定值的电源。针对AVS电源供电需求，很多厂商研究开发的多相电源芯片广为使用，是通过读取芯片的厂商标识(VID，Vendor IDentification)的值来确定芯片的供电电压。针对固定电压的电源需求是通过线性稳压器(LDO)或开关稳压芯片进行处理的。上述是目前所采用的芯片供电方式，但是这两种方式还是避免不了因芯片的电源需求种类多，差异大，上电时序要求高等所带来的繁琐的电路设计及可靠性问题。The on-board power supply design is based on the chip used. The power requirements of the chip used are all marked in the data sheet and are roughly divided into two types, AVS power supply and fixed value power supply. For the AVS power supply requirements, many manufacturers research and development of multi-phase power chips widely used, by reading the chip's manufacturer identification (VID, Vendor IDentification) value to determine the chip's supply voltage. Power requirements for fixed voltages are handled by linear regulators (LDOs) or switching regulators. The above is the chip power supply method currently used, but these two methods can not avoid the cumbersome circuit design and reliability problems caused by the variety of power requirements of the chip, large differences, and high power-up timing requirements.

具体实施方式detailed description
在中国专利《一种精密调压稳压器》，申请号：CN200810200051，申请日期：2008.09.18中描述了一种精密调压稳压器，满足高压电源的精密调压稳压需求，该稳压器包括低压补偿调控电路、采样电路、比较器、控制电路、隔离驱动电路、调整电路、电子开关、D/A电路、CPU电路；当CPU输出数字电压信号后，D/A将其转换的电压信号，送入比较器中，比较器将送来的基准电压与采样来的电压进行比较，通过控制电路、隔离电路后将电子开关闭合，让整流后的100Hz电压通过，使采样端的电压升高到基准电压值。这个专利与旧式机械调压器相比，其优势是体积小、重量轻、调压精度高，输出电压连续可调、可直接与单片机等相连实现程控稳压电源，有一定的经济效益。但是该专利所述的电源仅是电源模块的一种实现 方式，目前已经被电源芯片所取代，并且这种电源并不具备电源总线并与目标芯片通信来确定电源需求及上电时序，因此并不能解决目前单板电源设计复杂的问题。In the Chinese patent "a kind of precision voltage regulator", application number: CN200810200051, application date: 2008.09.18 describes a precision voltage regulator to meet the precision voltage regulation requirements of high voltage power supply, the stability The pressure device includes a low voltage compensation control circuit, a sampling circuit, a comparator, a control circuit, an isolation driving circuit, an adjustment circuit, an electronic switch, a D/A circuit, and a CPU circuit; when the CPU outputs a digital voltage signal, the D/A converts it. The voltage signal is sent to the comparator, and the comparator compares the sent reference voltage with the sampled voltage. After the control circuit and the isolation circuit, the electronic switch is closed, and the rectified 100 Hz voltage is passed, so that the voltage at the sampling end rises. High to the reference voltage value. Compared with the old mechanical pressure regulator, this patent has the advantages of small size, light weight, high voltage regulation precision, continuous adjustable output voltage, and can be directly connected with a single-chip microcomputer to realize a program-controlled power supply with certain economic benefits. However, the power supply described in this patent is only an implementation of the power module. The method has been replaced by a power chip, and the power supply does not have a power bus and communicates with the target chip to determine power supply requirements and power-on timing, and thus cannot solve the problem of complicated design of the current single-board power supply.
英飞凌等几家芯片厂商推出的开关电源稳压控制芯片一般是基于SMBUS总线接口，来通过CPU进行控制输出不同占空比的方波，方波驱动MOS管输出得到设定的电压，但是只能同时输出一种电压值，为芯片供电需要多个此类电源芯片，且不能控制上电时序及通信获取整个芯片的电源需求。The switching power supply voltage regulator control chip introduced by several chip manufacturers such as Infineon is generally based on the SMBUS bus interface to control the output of square waves with different duty cycles through the CPU. The square wave drives the MOS tube output to get the set voltage, but Only one voltage value can be output at the same time. It is necessary to supply multiple such power chips for the power supply of the chip, and it is not possible to control the power-on timing and communication to obtain the power requirements of the entire chip.
