1. A temperature control method for a power supply conversion chip, being applied to a controller in a multi-phase power supply, wherein each power supply conversion chip in the multi-phase power supply comprises an accumulator having
a first end connected to a current feedback end of the power supply conversion chip,
a second end connected to a temperature feedback end of the power supply conversion chip, and
an output end connected to a current signal input end of the controller,
wherein the accumulator is configured to send a current temperature accumulation value after adding a current detection value and a temperature detection value of the power supply conversion chip to the controller, and temperatures of power supply conversion chips increase as output currents increase and decrease as the output currents decrease; and
the method comprising:
calculating a real-time average value of the current temperature accumulation values sent by the power supply conversion chips; and
adjusting the output current of the power supply conversion chip with the current temperature accumulation value not equal to the real-time average value, whereby the current temperature accumulation value of the power supply conversion chip is the real-time average value.
