The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
As shown in Figure 1, a kind of hybrid power automobile air conditioner compressor control system comprises that engine 1, transmission device 2, battery 3, compressor 4, controller 5 and electricity drive conversion equipment 10.
In the present embodiment, transmission device 2 adopts belt transmission structure, compressor 4 adopts direct current compressor, has permanent magnetic brushless in the compressor 4, compressor 4 both can have been realized being driven by controller 5 electricity also can be by engine 1 belt drives, compressor 4 can only move a kind of mode when working at every turn, and compressor 4 drives conversion equipment 10 by electricity and switches mutually between engine 1 driving and controller 5 drivings.
As shown in Figure 1, engine 1 is connected with transmission device 2, the other end of transmission device 2 is connected with compressor of air conditioner 4 by electromagnetic clutch 6, engine 1 inputs to compressor 4 with power by transmission device 2, electromagnetic clutch 6, carries out the gas compression thereby make belt pulley drive the running of compressor 4 motor internal.
Wherein, electromagnetic clutch 6 is electrically connected with controller 5, by controller 5 controls, when Vehicular accumulator cell 3 no electricity or brownout, controller 5 will be controlled electromagnetic clutch 6 adhesives, and compressor 4 just switches to by engine 1 and drives, when Vehicular accumulator cell 3 chargings are finished, controller 5 will be controlled electromagnetic clutch 6 and separate, thereby disconnects the transmission of power between engine 1 and the compressor 4, is all controlled automatically by controller 5.
The power input of controller 5 is connected to the output of battery 3, and directly to controller 5 output DC288V ± 50V dc sources, compressor 4 is under electrically driven (operated) situation, fully by controller 5 control runnings by battery 3.Wherein, the running of controller 5 control compressors 4 can be adopted any mode of the prior art, does detailed description here no longer in addition.
As shown in Figure 2, electricity drives conversion equipment 10 and is made up of the three-phase two-way switch 7 and the rectification circuit that are arranged at compressor 4U, V, W end, the output of rectification circuit is electrically connected with battery 3, and three-phase two-way switch 7 is electrically connected with controller 5, and the action of three-phase two-way switch 7 is by controller 5 controls.Also connect a voltage regulator 8 in the rectification circuit, voltage controller 8 is made up of a contact switch K and a coil 9.
Rectification circuit comprise by three altogether the three-phase half controlled bridge formula rectification circuit formed of anode silicon diode VD1, VD2, VD3 and three common cathode IGCT VT1, VT2, VT3, the three-phase full wave rectifier circuit of forming by silicon diode VD1-VD6, reach filter capacitor C1 and C2.Wherein, the output of three-phase full wave rectifier circuit is electrically connected respectively with the control utmost point of IGCT VT1, VT2, VT3 by the contact switch K in the voltage controller 8, for the control utmost point of IGCT VT1, VT2, VT3 provides trigger voltage, the coil 9 in the voltage controller 8 also is connected in the output of three-phase half controlled bridge formula rectification circuit.
