Problems solved by technology
For example, a single switching power supply is used to supply power to the control system. When the air conditioning unit is installed and operated, it will be directly affected by the surrounding environment or other external human factors. The feedback loop of the control system responds to various influences. Frequent changes in the output voltage of the control system are relatively strong, which in turn affects the input and output of the power supply, reduces the effect of the switching power supply and increases the fluctuation of the power supply voltage, causes the instability of the control system operation, and affects the service life of the control system

The invention provides a power source device, a control method and system for power source output voltage and a unit. The power source device includes a power supply module and a voltage compensationmodule. The power supply module is used for outputting work voltage to loading equipment, obtaining load feedback voltage signals corresponding to the loading equipment and conducting adjustment on the work voltage on the basis of the load feedback voltage signals; the voltage compensation module is used for obtaining power supply feedback voltage signals output by the power supply module, generating work voltage compensation signals according to the power supply feedback voltage signals and sending the work voltage compensation signals to the power supply module to compensate for the work voltage. According to the power source device, the control method and system and the unit, by applying a power supply pattern of the multilevel power supply module to ensure the stability of output voltage, voltage fluctuation of a power supply can be reduced, the stability of the loading equipment is improved, the service life of products is prolonged, the quality of the products is improved, and the use feeling of users is improved.
Description
technical field [0001] The invention relates to the technical field of power supplies, in particular to a power supply device, a control method for the output voltage of the power supply, a control system and an equipment unit. Background technique [0002] At present, the power supply mode of the control system and other components of the equipment unit adopts a single power supply mode, and the equipment unit can be a commercial air conditioner unit or the like. For example, a single switching power supply is used to supply power to the control system. When the air conditioning unit is installed and operated, it will be directly affected by the surrounding environment or other external human factors. The feedback loop of the control system responds to various influences. Frequent changes in the output voltage of the control system are relatively strong, which in turn affects the input and output of the power supply, reduces the effect of the switching power supply and incr...
