Abstract
There is provided a power supply device 100 for switching power to an output line 150 between a first power supply 120 and a parallel second power supply 122. The power supply device 100 comprises: a first converter 130 connected to the first power supply 120 and configured to output a first voltage in a first predetermined range; and a second converter 132 connected to the second power supply 122 and configured to output a second voltage in a second predetermined range. The outputs of the first and second converters 130, 132 are connected together on the output line 150, and the first and second converters 130, 132 are arranged to maintain a voltage on the output line 150 within a third predetermined range.
