Abstract:
1. A voltage supplying apparatus, used to output a total output voltage, comprising: a fuel cell used to output a first output voltage; a DC-DC Voltage Converter used to receive said first output voltage and perform a conversion of said first output voltage to a second output voltage, where a positive input terminal of said DC-DC Voltage Converter and a negative input terminal of said DC-DC Voltage Converter are electrically connected with a positive output terminal of said fuel cell and a negative output terminal of said fuel cell respectively, a positive output terminal of said DC-DC Voltage Converter is electrically connected with a negative output terminal of said fuel cell, and a positive output terminal of said fuel cell with a negative output terminal of said DC-DC Voltage Converter are used to supply said total output voltage, wherein said total output voltage equal to the sum of the first output voltage and the second output voltage; and a control circuit used to control the voltage conversion of said DC-DC Voltage Converter.
