Abstract

The invention provides a power supply device. The power supply device comprises a power supply cabinet, a plurality of radiators, and a power conversion circuit, wherein the power conversion circuit is located in the power supply cabinet; the power conversion circuit comprises at least one of an alternating current-direct current conversion circuit and an alternating current-alternating current conversion circuit; the alternating current-direct current conversion circuit at least comprises a first rectification module, a first inversion module, a first filtering module, a first transformer anda second rectification module which are electrically connected in sequence; the alternating current-alternating current conversion circuit at least comprises a third rectification module, a second inversion module, a second filtering module and a second transformer which are electrically connected in sequence; the first rectification module, the first inversion module, the second rectification module and a first capacitor unit in the alternating current-direct current conversion circuit and the third rectification module and the second inversion module in the alternating current-alternating current conversion circuit are all located in the sealed chamber. The waterproof, moistureproof and dustproof functions can be achieved, core elements cannot be eroded and damaged even if the device isused in a severe environment, and the application range of the device is greatly expanded.

Description

technical field [0001] The invention relates to the technical field of power supplies, in particular to a power supply device. Background technique [0002] With the rapid development of power electronics technology, power supply devices have been widely used in various industries, such as electric vehicle charging piles, aircraft ground power supply (here the aircraft ground can be land, or the deck of a ship, etc.), etc. . In the existing power supply device, all components are generally integrated on the same support board or circuit board. When some components are damaged, it is not convenient to replace them; The wiring is more complicated, the interference is more serious, and the performance is poor; at the same time, all the components of the existing voltage device are exposed to the environment in the process of use, and in the harsh environment (for example, marine environment, etc.) When used, the core element is easily damaged by erosion. Existing power suppl...
