POWER SUPPLY CONVERSION SYSTEM AND METHOD OF CONTROLLING THE SAME

摘要

A power supply conversion system receives an external power source to supply power to a load. The power supply conversion system includes at least one main power apparatus, at least one auxiliary power apparatus, a main switch, an auxiliary switch, and a control unit. The control unit turns on the main switch to restore the external power source when the control unit detects that the external power source is normally restored, and jointly supply power to the load with the auxiliary power apparatus. Especially, the output voltage of the main power apparatus is greater than the output voltage of the auxiliary power apparatus. In addition, the control unit disconnects the auxiliary power apparatus supplying power to the load when the control unit detects that the main power apparatus completely supplies power to the load.

主权项

1. A power supply conversion system receiving an external power source and supplying power to a load, the power supply conversion system comprising:
at least one main power apparatus; at least one auxiliary power apparatus; a main switch connected between the external power source and the main power apparatus; an auxiliary switch connected between the auxiliary power apparatus and the load; and at least one control unit connected to the main power apparatus and the auxiliary power apparatus; wherein the control unit is configured to turn on the main switch when the control unit detects that the external power source normally supplies power so that the main power apparatus is configured to receive the external power source and convert the external power source to supply power to the load; the control unit is configured to turn off the main switch when the control unit detects that the external power source abnormally supplies power so that the external power source is disconnected to supply power to the load and the auxiliary power apparatus is configured to supply power to the load; the control unit is configured to turn on the main switch to restore the external power source so that the main power apparatus and the auxiliary power apparatus jointly supply power to the load when the control unit detects that the external power source is restored to normally supply power, wherein the control unit is configured to control that the output voltage of the main power apparatus is greater than the output voltage of the auxiliary power apparatus; the control unit is configured to disconnect the auxiliary power apparatus supplying power to the load when the control unit detects that the main power apparatus completely and fully supplies power to the load.
