Abstract: A power supply apparatus includes a first power module, a second power module, an energy storage module, and a controller. An output terminal of the first power module is connected in parallel to an output terminal of the second power module, which is then connected to a load, and load dynamic response performance of the second power module is better than load dynamic response performance of the first power module. The energy storage module is connected to the output terminal of the first power module and connected between a midpoint of the load and a reference ground. The energy storage module is configured to store electric energy and supply power to the load. The controller is configured to, in response to the load being in a dynamic change status, control the second power module to supply power to the energy storage module.
