AC/DC dual-output mobile power supply system

Abstract

The invention discloses an AC / DC dual-output mobile power supply system, which comprises a power supply unit, an inverter IC unit, an AC output unit and a DC output unit, wherein the power supply unitis used for charging the system; the inverter IC unit is connected with the power supply unit, the DC output unit and the AC output unit respectively; the inverter IC unit is used for selecting the DC output unit to output high-voltage DC or selecting the AC output unit to output AC according to load properties; the AC output unit is used for outputting AC; the input end of the DC output unit isconnected with the output end of the AC output unit; and the DC output unit is used for outputting high-voltage DC. The AC / DC dual-output mobile power supply system can output AC or DC according to needs of different devices, and the problem that the device is damaged thermally caused by use of a power supply only generating AC can be solved.

Description

technical field [0001] The invention relates to the technical field of mobile power supplies, and more specifically, relates to an AC and DC dual-output mobile power supply system.

Problems solved by technology

[0003] AC inverters are usually used in hospital information applications where there is a lack of mains power and where mobility is required, and the loads are also varied. When users use inverters, most users will bring some adapters and For capacitive loads such as computer cases, X capacitors will be connected in parallel to the input terminals of these loads. When the load is too large, the output MOS tube of the inverter power supply will overheat, resulting in overheating, which cannot be loaded for a long time and will seriously damage the product. At the same time, most of the current medical electronic products There are many kinds of adapters used in computer products, which will cause low-frequency noise in electronic products and computer products using AC inverter power systems.
