OUTPUT VOLTAGE FEEDBACK DEVICE FOR BEING USED IN A POWER SUPPLYING APPARATUS AND POWER SUPPLYING APPARATUS PROVIDED WITH THE SAME

摘要

The present invention relates to an output voltage feedback device for being used in a power supplying apparatus and a power supplying apparatus provided with the same. The power supplying apparatus provides electrical power via a wire set which includes a high level wire and a low level wire. The output voltage feedback device is provided with a voltage sensor and feedback unit for determining the voltage difference between the high level wire and the low level wire and the resultant measurement is transmitted back to the converter main body via the wire set in the form of a distinct electrical signal. The output voltage feedback device according to the invention can accurately determine the output voltage from the power supplying apparatus and, in case of occurring an output fault, interrupt the supply of power or enable an automatic compensation to reduce damage.
