Description
Technical field
The present invention relates to field of air conditioning, in particular to a kind of air-conditioner set control method and device.
Background technology
Nowadays, started extensive use Switching Power Supply in all kinds of electric equipment products, but, be easy in Switching Power Supply of the prior art produce larger power supply ripple value.As air-conditioner control system, complex structure, comprising load also more, if each load action simultaneously common source, ripple value then may be caused to exceed acceptable scope, and then directly having influence on the working condition of air-conditioner set controller, the reliability of air-conditioner set also cannot obtain effective guarantee simultaneously.Thus, with regard to needing, filtering process is done to the circuit in Switching Power Supply, to control the impact that power supply ripple value causes air-conditioner set.
At present, the control principle of existing Switching Power Supply 102 as shown in Figure 1, Switching Power Supply generally has multiple-channel output, wherein power supply exports 104 and is mainly used in driving load 108, load 110, power supply exports 106 for driving load 112, wherein, the power source loads of power supply output 104 is the heaviest, thus it can be used as the primary feedback of Switching Power Supply 102.Further, the principle that Switching Power Supply regulates is that the voltage change exported on 104 by power supply feeds back in switching power source chip, and with by-pass cock frequency or dutycycle, thus stabilized power source exports the voltage on 104.As shown in Figure 1, when Synchronization Control is carried out in controller 114 pairs of loads 108 and load 110, now power supply output 104 pack heaviest when load 108 and load 110 start, power supply exports 104 voltages and is dragged down.Now Switching Power Supply is dragged down to voltage according to primary feedback electric circuit inspection, then switching power source chip can heighten output frequency or dutycycle, exports 104 effects to reach stabilized power source.Due to power supply output 104, and power supply output 106 shares magnetic cores and reference point is consistent, now switching power source chip heightens frequency or dutycycle, improve elementary input power, according to coupling principle, this can cause power supply output 106 moment upper punch, and power supply ripple value will become large; When controller 114 pairs of loads 108, load 110 synchronously stop, now power supply output 104 shows as load transients and lightens, power supply exports 106 heavier loads, power supply exports 104 voltages and can raise, now switching power source chip detects that primary feedback voltage raises, therefore switching frequency is turned down or dutycycle is turned down, export 104 with stabilized power source.Because switching frequency and dutycycle diminish, primary input power diminishes, and now power supply exports the pack heaviest of 106, and power supply can be caused to export 106 and dragged down, power supply ripple value will become large simultaneously.
Further, in order to control power supply ripple value, the various wave filters that Switching Power Supply mainly relies on electric capacity, inductance to form.Known by the principle of above-mentioned Switching Power Supply, when controlling the start-stop of motor, the power supply ripple of air-conditioner set can become large, at this moment just need carry out passive filtering process by external a lot of electric capacity, inductance, to reach the object controlling power supply ripple.But, when adopting the power supply ripple controlling air-conditioner set breaker in middle power supply in such a way, not only increase and control cost, and also poor to the control effects of power supply ripple.Because when power supply ripple value is increased to higher value, the quantity of electric capacity that can be external or inductance is limited, so then cannot ensure the effective control to power supply ripple.
For the problem proposed in prior art, at present effective solution is not yet proposed.
