PSU, Power Supply Unit, Power Supply.
Bootloader, boot loader, is an online upgrade function.
PFC, Power Factor Correction.
LLC Resonant Converters, is a Resonant converter.
With the continuous development of the internet, the demand and sharing of information for various industries are increasing, the number and scale of data centers providing information services for various computers are expanding rapidly, the number of servers is increased by times due to the continuous expansion of the existing machine rooms, and the problem of maintenance is caused. In order to solve the problem, a server power supply manufacturer adds an online upgrading function, namely a bootloader function, and the function can realize the upgrading of power supply software under the condition of not disassembling a power supply, thereby greatly improving the working efficiency and saving the manpower.
For the current server power supply, a topological structure of PFC + LLC is mostly adopted, so that PFC forms a front stage, LLC is a rear stage, the front stage and the rear stage are respectively controlled by using a different single chip microcomputer, and data interaction is performed between the front stage and the rear stage through a serial port or other communication ports. The LLC back stage directly communicates with a backboard controller BMC of the server through the golden finger board, and when bootloader upgrading is carried out, not only the MCU program of the LLC back stage needs to be upgraded, but also the MCU program of the front stage PFC needs to be upgraded according to requirements. Because the host can only communicate with the LLC through a golden finger and the basic functions of the existing bootloader can only upgrade one MCU online through the bootloader, the bootloader cannot be used for upgrading the front stage at present.
