Problems solved by technology

At this time, since the load of another group of power supplies is aggravated, it is likely to cause an excessive voltage drop (voltage drop) in the power supplied by this group of power supplies.
If the power suddenly drops below the minimum power specification of the electronic product, it may cause the electronic product to shut down without warning, or cause the electronic system to be very unstable

Abstract

The invention provides a power supply device. The power supply device comprises two groups of power supplies which are connected together in parallel to supply power required by the running of an electronic product at the same time. The power supply device provided by the invention can stably / accurately output expected DC output voltage to the electronic product for utilization; and in the over-voltage of one group of power supplies, main power internally produced by the other group of power supplies can be boosted in advance to avoid the excessively great voltage drop of the DC output voltage.

Description

technical field [0001] The present invention relates to a power supply device, and in particular to a power supply device with functions of external overvoltage compensation and / or current detection and feedback compensation. Background technique [0002] In the application of some high-end electronic products (such as servers and industrial computers), two sets of power supplies with the same specifications and negative feedback control function are often connected together to supply the electronic products simultaneously. power required. When one of the power supplies fails due to overvoltage, another set of power supplies is used to continuously supply power to the electronic products. [0003] In fact, when one of the power supplies is overvoltage, or the feedback of the two power supplies is deviated, due to the negative feedback control, the control signal generated by the voltage feedback controller inside the power supply The working cycle of the power supply will ...
