Power supply output power compensation method and device

The invention provides a power supply output power compensation method and device, which are applied to power supply equipment capable of outputting at least two types of power supplies, and when the power supply equipment outputs a first type of power supply and a second type of power supply at the same time, if the output power value of the first type of power supply reaches a preset power value, the power supply equipment outputs the first type of power supply. And monitoring an output power value of the first type of power supply in real time, and distributing a power value to the first type of power supply based on a second quota value when the current output power of the first type of power supply exceeds the first quota value. According to the scheme provided by the invention, by reserving the quota values of the two types of power supplies, the power can be automatically allocated, the use efficiency of the power supplies is improved, and the reasonability of power supply distribution is ensured, so t
