Motor, according to the output power of blowerIt is found that the premise constant in motor number of pole-pairs and electromechanics frequency
Under, to reach same output power, motor magnetic linkage is increased, then electric current is far below low voltage motor.
Wherein, p is motor number of pole-pairs, ψsFor motor magnetic linkage, isFor current of electric, Ω is electromechanics frequency.
Meanwhile the loss of electric machine includes winding copper loss PCu, core loss PFe, mechanical loss PfωWith stray loss Ps.Wherein,
Winding copper loss PCu=3is 2R, R are winding resistance, square directly proportional to current of electric.So when the current decreases, motor copper
Consumption decreases, and the efficiency of motor is improved, while interference caused by electric current is also small very much.
Such as: blower directlys adopt power accumulator power supply, and electric current very little on conducting wire, interference is smaller, and electric efficiency is opposite
It is higher.
Such as: blower directlys adopt power accumulator power supply, eliminates DC_DC module (such as: DC/DC converter 7), wind
Engine efficiency improves 5% or so.
Such as: the electric current on blower conducting wire reduces, and reduces since the near-field coupling generated on blower line and far field couple, mentions
The reliability of high entire blower fan system, and by reducing di/dt, improve the Electro Magnetic Compatibility of entire drive system.
As it can be seen that example shown in Figure 2, cavity interior mainly high direct voltage signal and low current signal, EMI is good,
Without DC/DC converter, so that the fan efficiency of the blower fan control system of the air-conditioning is highly improved.
That is, the blower fan control system of the air-conditioning is directly powered with power accumulator, DC/DC transformation is needed not move through
Device, while the electric current of blower motor significantly reduces, it can be with save the cost while improving energy efficiency；It can solve driver
Because the long and resulting electromagnetic interference of the conducting wire in blower will affect entire driving device working status, so that air-conditioning system
Reliability enhancing, can also promote the stability of air-conditioning system.
Example shown in Figure 2 as a result, power accumulator 4 in addition to module (such as: master control and compressor drive
6) power supply is outer, also in evaporator and condenser cavity blower and driver power, what is connected between blower and driver leads
Line is very short, and high-frequency switching signal influences smaller, and the intracorporal conducting wire of chamber is mainly power accumulator DC bus, DC electric current very little,
To the interference very little of the blower fan control system of the air-conditioning；Due to the electric current very little of monomer blower, so the efficiency of blower is higher；It should
The blower fan control system of the air-conditioning needs not move through DC/DC converter, reduces loss, has saved cost.
In an optional example, example shown in Figure 3, the blower fan control system of the air-conditioning may include: master control
(such as: master control and compressor drive 6), blower driving (such as: evaporation fan driver 12 and condensation fan driver 22),
Blower motor (such as: the motor of evaporation fan 11 and the motor of condensation fan 21), DC-DC module (such as: DC/DC converter
7)。
It is alternatively possible to referring to control mode as shown in Figure 4, voltage is through DC-DC module (such as: DC/DC converter 7)
It after boosting, is supplied to evaporation (condensation) driver (such as: evaporation fan driver 12 and condensation fan driver 22), control is steamed
Hair (condensation) blower (such as: evaporation fan 11 and condensation fan 21).
Such as: by DC/DC by power accumulator voltage transformation to middle pressure, while electric current is small on ensuring conducting wire, also
Fan driver cost can be further decreased.
Wherein, medium voltage network, may include: by DC/DC converter will be above 400 volts power battery (such as: power
Battery 4) voltage transformation is the voltage between 300 volts to 400 volts, the power supply for evaporation fan 11 and condensation fan 21.
As it can be seen that the electric current by conducting wire can be greatly reduced by using middle high-pressure blower, fan efficiency is promoted, is reduced
Interference caused by high current.
In an optional example, the blower fan control system of the air-conditioning when using high voltage supply mode, is then not necessarily to DC/DC
Converter 7.If using medium-pressure electricity supply mode, need by DC/DC converter 7 export in press, range can 300 volts~
Between 400 volts, the pressure voltage of Drive Module (such as: evaporation fan driver 12 and condensation fan driver 22) is reduced
(only 600 volts of modules and 1200 volts of modules in industry), can choose the lower module of pressure resistance, to further save cost.
Such as: the power supply of in general power accumulator is all high pressure, when considering save the cost, is just used
High pressure is become middle pressure by DC/DC converter, and pressure is used to drive corresponding Middle pressure draught fan in this.
Wherein, power accumulator be whole system (such as: the blower fan control system or even entire air-conditioning of the entire air-conditioning
System) power supply, therefore the selection of power supply needs the power demands of each component of comprehensive consideration whole system, cannot only consider
Blower, therefore be necessary using medium-pressure electricity supply mode through DC/DC converter 7.
In an optional example, the blower fan control system of the air-conditioning, all blowers and air-conditioner control system are carried out solely
Vertical control, can promote the efficiency of air-conditioning system.
Such as: since each blower is adapted to individual fan driver so that the blower fan control system of on-board air conditioner with
Air-conditioner control system relatively independent can be controlled, and then can individually control blower and/or individually control sky according to demand
It adjusts, is conducive to the efficiency for promoting on-board air conditioner.
