According to the physical location relationship between the Power supply and the device, we can roughly divide the power supply into two categories: External power supply and Internal power supply (power Supplies - external/internal (Off-Board)). External Power Supplies are power supply units independent of the main body of the device. It is usually connected to the main device via a power cord and is responsible for converting the mains power into DC or AC power suitable for the device. The design of the external power supply takes into account the portability and versatility, so that the same power supply can be adapted to a variety of devices, reducing the overall cost and maintenance difficulty of the equipment. Internal Power Supplies refers to power modules that are directly integrated inside the device and are responsible for converting external input power into power required by the device. They are usually encapsulated inside the enclosure of the device and connected to the various components of the device through internal circuits.
