Reference picture 1, Fig. 1 are the transducer air conditioning control method that first embodiment of the invention provides based on transducer air conditioning
Control device electrical block diagram, for convenience of description, the part related to the embodiment of the present invention is illustrate only, be described in detail such as
Under：
Transducer air conditioning control device includes first resistor R1, gate-controlled switch K, voltage detecting circuit 10, rectifier 20, electricity
Solve electric capacity E1, load 40 and controller 30, it is one defeated to be series at one end of input AC electricity and rectifier 20 by first resistor R1
Between entering end, the rectifier 20 has two inputs, and one of input can connect AC power by first resistor R1
Live wire, rectifier 20 another input connection AC power zero line, gate-controlled switch K is in parallel with first resistor R1, whole
Flow device 20 to be used to carry out the alternating current of input rectification output DC voltage, DC voltage is powered load 40, voltage inspection
Slowdown monitoring circuit 10 is used for the input ac voltage value for detecting transducer air conditioning control device, and controller 30 is examined according to voltage detecting electric current
The voltage value control gate-controlled switch K actions of survey, to control DC voltage to charge electrochemical capacitor E1；Control method bag
Include：
Step S10, sample detecting ac voltage；
Step S20, when ac voltage is less than the first preset value, control gate-controlled switch disconnects, to control DC voltage
Electrochemical capacitor is charged by first resistor R1；
Step S30, when ac voltage is higher than the second preset value, control gate-controlled switch K closures, to control DC voltage
Electrochemical capacitor E1 chargings are terminated by first resistor R1, wherein the second preset value is more than the first preset value.
The transducer air conditioning control device of the present embodiment can be applied to outside transducer air conditioning room in control circuit, for room
The work of outer load provides power supply, as alternating current input power supplying pass through it is defeated after the above-mentioned rectification of rectifier 20 and electrochemical capacitor E1 filtering
Go out DC bus-bar voltage, it is right for dc source of the outdoor load as described in compressor, outdoor fan motor even load provide work
For AC-input voltage is 220V, its DC bus-bar voltage can reach 300V or so, because compressor load operating current is big,
Therefore for electrochemical capacitor E1 capacity is bigger such as with the convertible frequency air-conditioner on-hook of 1, its electrochemical capacitor E1 capacity is 800uF,
Pressure-resistant 450V.
The voltage detecting circuit 10 of the present embodiment is arranged on ac power input end, for detecting the alternating current of AC power
Pressure value, specifically, as a kind of particular circuit configurations of voltage detecting circuit 10, as described in Figure 1, voltage detecting circuit 10 includes
Second resistance R2 and 3rd resistor R3, second resistance R2 one end connection alternating current L lines, second resistance R2 other end connection the
Three resistance R3 one end, 3rd resistor R3 other end connection alternating current N lines, second resistance R2 and 3rd resistor R3 tie point
For the output end of voltage detecting circuit 10, its output end is connected to controller 30, i.e., voltage detecting circuit is using simple partial pressure electricity
The implementation of resistance detects alternating voltage, certain voltage detecting circuit 10 can also use other circuit form such as by using
The mode of isolating transformer detects, and will not be repeated here.
The first resistor R1 of the present embodiment can use powerful PTC resistor or cement electricity in real work application
Resistance, plays decompression metering function.
The transducer air conditioning control device of the present embodiment normal work it is upper electric when, the controlling switch K of controller 30 disconnect,
Now AC power is charged through PTC resistor R1 by rectifier 20 to electrochemical capacitor E1, due to PTC resistor R1 following temperature rising
The big characteristic of resistance, if its resistance can increase when charging current is big, therefore play a part of limiting charging current, be not in
Big charging current causes its damage when passing through rectifier 20.The preset time such as 10 determined between when charging by an experiment
It can determine that its electrochemical capacitor E1 fills with voltage after second, i.e. the DC bus-bar voltage at its both ends reaches stationary value as input
Its DC bus-bar voltage reaches more than 300V i.e. it is believed that reaching stationary value charging complete for 220V AC voltage, now controls again
Gate-controlled switch K processed is connected, and alternating current input power supplying directly provides power supply by gate-controlled switch K to late-class circuit, with this controller 30
Related load such as compressor etc. can be controlled to act.
In practical work process, the alternating voltage of input can there is a situation where unstable, and it is quick voltage particularly occur
When fluctuating big, such as there is voltage and fall rapidly and recover normal continuous state, now for existing control, by
Electrochemical capacitor E1 charging completes may proceed to control gate-controlled switch K closures, due in voltage falling in having controlled gate-controlled switch K
When falling big such as the alternating voltage of input side drops into below 80V, and now the DC bus-bar voltage at electrochemical capacitor E1 both ends also can be with
Decline it is serious, if AC-input voltage can so form big instantaneous charging followed by rapid increase to electrochemical capacitor E1
What electric current exceeded rectifier 20 bears to cause when voltage so works for a long time its damage, while be also well over can for this charging current
Control switch K operating current is easily caused its damage when so working for a long time.
Therefore in the transducer air conditioning control method of the present embodiment, alternating voltage is detected by voltage detecting circuit 10 in real time
Value, that is, the instantaneous value of alternating voltage is detected, when the voltage for occurring above-mentioned, which quickly fluctuates, causes voltage to fall rapidly, if
During less than the first preset value, control gate-controlled switch K is disconnected, and now first resistor R1 is accessed, when AC-input voltage is followed by fast
When speed rises, now AC-input voltage is charged by the rectified devices 20 of first resistor R1 to electrochemical capacitor E1, due to the
One resistance R1 metering function, therefore charging current will not be caused too high and cause the damage of rectifier 20.If voltage rises
To more than the second preset value of safety, then can confirm now electrochemical capacitor E1 both ends voltage have increased to safety value thus this
When charging current can be reduced to safety value, now control gate-controlled switch K closure, that is, control first resistor R1 to enter electrochemical capacitor E1
Row charging complete, hereafter alternating voltage can continue through gate-controlled switch K and electrochemical capacitor is charged, but now charging current has dropped
To below safety value, because according to the charge characteristic of electrochemical capacitor, the size of its charging current is that whose exponential curve rises, and is being filled
The electric current at initial stage of electricity is big, can be substantially reduced in the later stage electric current of charging, and magnitude of voltage is slower closer to stationary value curent change, because
If this detects that voltage has increased to more than safety value, its charging current is reduced within safety value, and passes through detection
Input alternating voltage rises to more than second preset value and can extrapolate the voltage at electrochemical capacitor E1 both ends and have increased to peace
More than total head, the damage of rectifier 20 will not be caused producing big charging current.Specifically, when input ac voltage is 220V
When, the first preset value span is determined by experiment as 75-85V such as desirable 80V, and the second preset value span is 125-
145V such as desirable 130V.
Be worth explanation when, here voltage detecting circuit 10 detect need be AC magnitude of voltage, rather than electrolysis electricity
Hold the d-c bus voltage value at E1 both ends, its reason is due to the cushioning effect of electrochemical capacitor E1 discharge and recharges, and its dc bus is electric
Pressure value can not reflect the quick situation of change of AC-input voltage value in real time, quickly be fluctuated if there is above-mentioned alternating voltage
When, d-c bus voltage value, which can correspond to, to be changed slowly a lot, therefore d-c bus voltage value can not monitor alternating voltage in real time
Situation of change causes controlling switch K action accurate not in time, and then can not realize that first resistor R1 charges to electrochemical capacitor E1
Metering function.
Further, when alternating voltage is risen to more than the second safe preset value, also continue to detect alternating voltage rising
To the duration of the second preset value of safety, when if above the second preset value and continuing preset time, controllable open just is controlled
Close K closures, can now further determine that alternating voltage be not in it is quick it is big fluctuate, if do not added above-mentioned lasting
The detection control of time, when voltage quickly fluctuates, quickly toggling during gate-controlled switch K controls may be caused, this
Sample can reduce switch K working life.It is 0.5-3S to be determined by experiment lasting preset time span, as value is
1S。
Further, when ac voltage is less than the first preset value, while control gate-controlled switch K disconnects, phase is also controlled
Close load to close, specifically can control the large current loads such as compressor, blower fan to close for transducer air conditioning, because being opened controllable
When closing K disconnection first resistor R1 accesses, if working on for above-mentioned large current load can cause first resistor R1 partial pressures too high
And the voltage in follow-up load is too low and causes it not work, when particularly first resistor R1 is PTC resistor, if it is electric
Stream causes greatly its resistance temperature rise to exceed Curie-point temperature value, and that its resistance can be caused to rise to is very high so that the partial pressure undertaken is very
High and follow-up loaded work piece voltage is pulled low causes it not work too much.
Transducer air conditioning control method provided in an embodiment of the present invention, by detecting ac voltage in real time, works as alternating current
When pressure value is less than the first preset value, control gate-controlled switch K disconnects, to control DC voltage by first resistor R1 to electrochemical capacitor
E1 is charged, and when DC voltage value is higher than the second preset value, control gate-controlled switch K closures, to control DC voltage to lead to
Cross first resistor R1 to terminate electrochemical capacitor E1 chargings, wherein the second preset value is more than the first preset value.The frequency conversion of the present invention is empty
Adjust device control method to occur in the alternating voltage of external world's loading big when fluctuating rapid, disconnect switch K accesses first in time
Resistance R1 so that first resistor R1 plays the charging current metering function to electrochemical capacitor E1, so as to avoid in the prior art
Control gate-controlled switch K electrochemical capacitor E1 when closing always charging current is excessive and damages the components such as rectifier, improves change
