Abstract
A power conversion device includes a DC-to-DC conversion circuit that receives and processes a DC power input and supplies a DC output of a predetermined voltage level, an output connector receiving the DC output and having power terminals to transmit the DC output and a plurality of level-selecting terminals, a terminal device having counterpart power terminals and a plurality of counterpart level-selecting terminals, which engage the power terminals and the level-selecting terminals of the output connector, respectively, a feedback circuit coupled to the DC-to-DC conversion circuit and connected to each level-selecting terminal by a resistor having a predetermined resistance to provide a feedback signal to the DC-to-DC conversion circuit which in turn changes the voltage level of the DC output, and a display circuit, which is coupled to the output connector to display the voltage level of the DC output at the power terminals of the output connector.
