Specific embodiment
Below in conjunction with the accompanying drawings, the specific embodiment of the present invention is further described.Following embodiment is only used for more
Technical scheme of the present invention is clearly demonstrated, and is not intended to limit the protection scope of the present invention and limits the scope of the invention.
Fig. 1 shows a kind of flow diagram of the method for inhibiting harmonic current of refrigerator provided in this embodiment, including：
S101, the compressor target frequency that refrigerator master control borad is sent is received, if judging to know the compressor target frequency
More than 0, then enabled instruction is sent to compressor.
Specifically, refrigerator master control borad is calculated in refrigerator according to environmental factors such as the current temperature of refrigerator, humidity and compresses
The theoretic frequency of machine, i.e. compressor target frequency；Then the frequency conversion board of refrigerator receives the compressor target that refrigerator master control borad is sent
Frequency simultaneously judges, if the compressor target frequency is more than 0, sends enabled instruction to compressor, makes compressor start.
Wherein, the compressor target frequency is refrigerator master control borad according to environmental factors such as the current temperature of refrigerator, humidity
The theoretical value of refrigerator inner compressor frequency is calculated.
It should be noted that the compressor is frequency-changeable compressor, the present embodiment is also adapted to it in addition to being adapted to refrigerator
Its frequency conversion freezing and refrigerating system product.
S102, the compressor horsepower after the compressor start is calculated according to the output voltage and output current of frequency conversion board,
If judgement knows that the compressor horsepower is more than or equal to threshold value, startup power factor correcting pfc circuit.
Specifically, the compressor is started according to the enabled instruction that frequency conversion board is sent, and frequency conversion board is according to change after startup
The output voltage and output current of frequency plate calculate current compressor horsepower and are judged, if the compressor horsepower is more than etc.
In threshold value, then start pfc circuit.
Wherein, the compressor horsepower is the current operation power that is calculated by frequency conversion board after compressor start.
The threshold value judges the whether qualified value of compressor horsepower to be predetermined.
The pfc circuit is to be integrated in for adjusting the circuit of the power factor of compressor in frequency conversion board, to inhibit to compress
The harmonic current of machine is allowed to meet international and domestic EMI standards requirement.
S103, current phase and voltage-phase according to frequency conversion board input, pass through the pfc circuit and adjust the change
The input current of frequency plate, so that the current phase of frequency conversion board input and voltage-phase matching, inhibit harmonic current.
Specifically, the compressor is frequency-changeable compressor, and the running frequency of the frequency-changeable compressor is continually changing, theory
The phase of the voltage and current of up-conversion plate input is identical, will not generate harmonic current, but in actual moving process, defeated
Higher hamonic wave can be generated by entering electric current, that is, generate harmonic current, when harmonic current is excessively high, will not meet international and domestic EMI
Standard requirement, it is therefore desirable to inhibit harmonic current.By the pfc circuit integrated in frequency conversion board, can be inputted according to frequency conversion board
Current phase and voltage-phase, to adjust the input current of frequency conversion board, the current phase and voltage-phase that enable compressor are use up
Measure it is identical, so as to inhibit harmonic current.

Two kinds of functions are made, is mutually independent of each other between two kinds of functions, reduces the rectification cost of existing product；It will be existing relatively independent
Working method becomes Collaborative Control, can realize frequency control and realize EMI current harmonics eliminations by PFC control functions,
Meet associated test standards, and can effectively reduce the power of refrigerator complete machine, reduce power consumption, improve power factor, reduce energy
Consumption and cost, and reduce the complexity of production.
The present embodiment in frequency conversion board by increasing pfc circuit, by frequency control with PFC control functions according to the fortune of refrigerator
Row power and startup-shutdown opportunity Collaborative Control, while the associated test standards of refrigerator can be met, reduce rectification cost and production
Difficulty；Start pfc circuit when compressor horsepower is more than or equal to threshold value, adjust the input current of frequency conversion board, input frequency conversion board

It should be noted that it is only to illustrate, and be not especially limited that the priority of above-mentioned steps S104-S106, which performs relationship,
It can be performed according to the combined in any order of three.
Specifically, after the frequency conversion board of refrigerator receives the compressor target frequency of refrigerator master control borad transmission, judged, if
Compressor target frequency is equal to 0, then out code is sent to the compressor, to reduce the power consumption of refrigerator.By further
The pfc circuit is closed, can further reduce the power consumption of refrigerator.
After the frequency conversion board of refrigerator receives the compressor horsepower of compressor transmission, judged, if the compressor horsepower
Less than threshold value, then illustrate that current harmonic current meets international and domestic EMI standards requirement, there is no need to inhibit harmonic wave electric
Stream, therefore by closing the pfc circuit, to reduce the power consumption of refrigerator.
Specifically, in the actual moving process of refrigerator, as shown in figure 3, frequency conversion board receives the transmission of refrigerator master control borad
Compressor target frequency when compressor target frequency is more than 0, opens compressor, and the frequency of compressor is gradually increased to by zero
Target frequency；During compressor frequency increase, power increases therewith, and the harmonic current of generation incrementally increases, and power factor gradually drops
It is low.
When frequency conversion board detects that the compressor horsepower of compressor is more than PFC startup powers, start pfc circuit, open PFC controls
Function processed inhibits harmonic current, improves power factor；The output of frequency conversion board frequency conversion simultaneously so that frequency conversion board can be defeated by frequency conversion
Go out and run simultaneously with PFC functions；As long as compressor horsepower is more than PFC startup powers, pfc circuit is kept it turned on.
When the compressor target frequency that frequency conversion board receives the transmission of refrigerator master control borad is 0, frequency conversion output is closed, stops becoming
Frequency compressor operating simultaneously closes off pfc circuit, reduces stand-by power consumption.
Frequency conversion board continues waiting for the instruction next time of refrigerator master control borad, so circulation is gone down under halted state.
The present embodiment realizes the frequency control of refrigerator and reduces the requirement of refrigerator complete machine EMI indices simultaneously, by frequency conversion
Control, according to the operation power of refrigerator and startup-shutdown opportunity Collaborative Control, reduces stand-by power consumption, reduces refrigerator with PFC control functions
Complete machine power, improving energy efficiency grade, while meet the associated test standards of refrigerator reduces cost and production difficulty.
