Title: POWER SUPPLY APPARATUS AND POWER SUPPLY METHOD
Abstract:
A power supply apparatus and a power supply method. The power supply apparatus comprises a power source (100), a direct current conversion circuit (200), a current output port (800), a power supply mode selection circuit (400), and a control circuit (500). The power supply mode selection circuit (400) is configured to generate a first power supply mode setting signal or a second power supply mode setting signal according to a connection manner between a load (700) and the current output port (800). The control circuit (500) is configured to control, when the first power supply mode setting signal is received, the direct current conversion circuit (200) so that same enters a first power supply mode and performs direct current conversion according to a first working frequency to output a first drive current, or control, when the second power supply mode setting signal is received, the direct current conversion circuit (200) so that same enters a second power supply mode and performs direct current conversion according to a second working frequency to output a second drive current. The power supply apparatus of the present invention has the advantages of a simple circuit structure and low costs.
