Abstract: The present disclosure provides a control method, in which charge control is combined with input voltage feedforward control and output current feedforward control. It can be shown that the combination of the charge control with the feedforward control performs better than the combination of the direct frequency control (DFC) with the feedforward control. In particular, the combination of the charge control with the feedforward control has much better load transient response with respect to the load transient response of the combined direct frequency control and feedforward control.

Abstract: The disclosure provides a network equipment power supply and a heat dissipation system therefor. The heat dissipation system includes a liquid-cooling heat dissipation device and an air-cooling heat dissipation device. The liquid-cooling heat dissipation device includes a liquid inlet, a liquid outlet, and a liquid-cooling pipe between them, wherein liquid-cooling medium flows inside the liquid-cooling pipe and takes away heat generated by components arranged around the liquid-cooling pipe; The air-cooling heat dissipation device includes an air inlet, an air outlet, and an air-cooling channel between them, wherein airflow passes through the air-cooling channel and takes away heat generated by components arranged around the air-cooling channel. The disclosure conducts hybrid heat dissipation combining characteristics of liquid-cooling heat dissipation and air-cooling heat dissipation to effectively enhance heat dissipation efficiency, and provides a new choice for design of a power supply unit with high power density.

Abstract: Embodiments of the present application provide an online program updating method, including: receiving an external command, acquiring an updated program file, and storing the updated program file into the backup area through a program in the application area, where the external command includes the updated program file, and running the updated program file when a program counter jumps to the backup area. This solution, after the program counter jumps to the backup area, runs the updated program file, thereby providing power continuously while updating the online program and improving the reliability of the power supply system.
