Problems solved by technology
In addition, in terms of temperature measurement of the power rectifier module, an infrared imager will be used to take pictures of the power rectifier module, and the current hot spot (hot spot) can be known by the relative temperature distribution on the image, but this cannot solve the problem of heat accumulation The problem
The above two methods are the power supply efficiency and temperature data obtained by human operation, so the measurement results are not accurate, which makes the output power supply effect not good, and the purpose of automatically adjusting the power supply efficiency cannot be achieved.

The invention provides a multi-phase power supply device and a current adjustment method thereof. The multi-phase power supply device can output different phases of voltage sources and current to a microprocessor to detect modules and adjust the current of various phases of voltage sources according to detected temperature of current various voltage sources and current sources so as to achieve the effect of heat balance. The multi-phase power supply device also has a function of automatically measuring the power efficiency, can be used for displaying the result ofthe detected temperature of various phases of voltage sources and the power efficiency on a screen to ensure that a user can conveniently know the working efficacy of the power supply device.
Description
technical field [0001] The present invention relates to a multi-phase power supply device, and in particular to a multi-phase power supply device with automatic adjustment of phase voltage temperature and automatic efficiency measurement. Background technique [0002] As the performance of the microprocessor increases, its power requirements also increase, and the required instantaneous current also increases. The traditional single-phase current supply can no longer meet the current system requirements. Current microprocessors, graphics and storage systems all use multi-phase power solutions, and the power supply device on the motherboard also supports the multi-phase power supply technology. Common multi-phase power supply devices include 4-phase and 8-phase power rectification modules (Voltage Regulator Module, VRM for short). The multi-phase power supply has the advantage of phase interleaving. By switching the phases at a uniform time interval, the output voltage wavef...
