Description

Smart power management unit

The present invention relates to a smart power management device, and more particularly to a power management device that can be embedded in an internal electronic device to enable a plurality of power supply outputs or control a single power output to provide a backup power application.

At present, the ATX (Advanced Technology Extended) specification is still the most common motherboard specification for electronic devices (mainly PC, NB). As shown in Figure 1, the power supply inside the electronic device is directly electrically connected to the ATX system board. The power supply is operated by the switch of the system board. The design of the ATX power supply is limited to the system configuration specifications, and the wattage of the power supply cannot be arbitrarily expanded. Therefore, in a large-sized electronic device (for example, 4U or more), the current practice is to install a separate device power supply (Redundant Power Supply) inside the chassis. The conventional backup power supply usually has at least two power supplies as a group, so the inside of the casing It is necessary to install a backup power supply, which makes the internal space of the casing crowded, and the maintenance is very inconvenient. Moreover, the heat dissipation is not easy, and the system board and its components are easily damaged. Therefore, the conventional backup power supply is provided. The practice needs to be improved.

Furthermore, in a smaller-sized electronic device (for example, 1U), it is more limited by the size of the casing, and the conventional backup power supply cannot be used. When the internal power supply of the system configuration is damaged, it needs to be disassembled. It is very inconvenient for the case to replace the new power supply.

In view of this, the main purpose of this creation is to propose a proper size, which can be directly embedded in the interior of the electronic device, thereby electrically connecting the internal and external power supply, and can be adjusted. A hybrid power management device that distributes or controls a single power output to a redundant power supply application.

In order to achieve the above object, the present invention provides a smart power management device, which has a voltage control circuit and is provided with at least two external ports and an internal port. The internal device can be electrically connected to an electronic device. The smart power management device is embedded in the electronic device, and one of the external devices is electrically connected to the power supply inside the electronic device, and the other external device is exposed outside the electronic device. The external power supply is connected to the power supply; wherein the voltage control circuit can detect and record the internal and external power supply conditions of the external connection, thereby configuring a plurality of power supply outputs or controlling a single power output.

Wherein, the external connection is provided with a foolproof mechanism to prevent the user from improperly protecting the power supply of the device and causing damage to the system and endangering its own safety.

The intelligent power management device further has an LED display interface for monitoring the power supply condition, and an insulating cover can be disposed on the system to properly isolate the system board and the components thereon, and can also be insulated to protect the user. Safety, the insulating housing is further provided with a plurality of heat dissipation holes.

In summary, the intelligent power management device of the present invention can be installed inside any size electronic device to electrically connect the internal power supply of the electronic device to supply system power, and more to reflect the total power requirement of the system. Connecting at least one external power supply to expand the total power of the system; further, the intelligent power management device can detect and record the internal and external power supply conditions of the external connection of the external power supply, thereby configuring multiple power output or control A single power output, if the internal power supply and the external power supply are both normal, the integrated power supply is evenly distributed to the power supply output, and when any one of the power supplies is damaged, it can be immediately switched to another normal power supply The power supply is separately supplied to achieve a lightweight and lightweight power backup function.
