The invention provides a charging system. The charging system comprises an AC-DC module, a DC bus, a first breaking device, a second breaking device, a first DC-DC module and a second DC-DC module. The AC-DC module is used for converting alternating current output by the alternating current source into direct current and outputting the direct current to the direct current bus; the second DC-DC module is used for performing voltage conversion on the direct current output by the direct current power supply and then outputting the direct current to the direct current bus; the first DC-DC module is used for obtaining the direct current from the direct current bus and outputting the direct current to a load after voltage conversion. By adopting the charging system, the breaking device in the charging system can provide effective insulation and ensure the safety of the system, meanwhile, the alternating current power supply branch circuit formed by the alternating current source and the AC-DC module and the direct current power supply branch circuit formed by the direct current power source and the DC-DC module in the charging system can be connected with the load through the direct current bus, the connection mode is simple, and the cost is low. The stability of the system is improved, and the design cost is reduced.
