Abstract
The invention relates to the technical field of vehicle-mounted refrigerators and particularly relates to a control structure of a brushless DC motor of a vehicle-mounted refrigerator. The control structure of the brushless DC motor of the vehicle-mounted refrigerator includes a rotating-speed regulator, a current regulator, a PWM synchronous controller, a three-phase PWM inverter, a current detecting device, a brushless DC motor, a counter-potential detection device and a rotating speed calculator. An output of the rotating-speed regulator is connected with the current regulator. An output of the current regulator is connected with the PWM synchronous controller. An output of the PWM synchronous controller is connected with the three-phase PWM inverter. The three-phase PWM inverter is connected with the brushless DC motor. The brushless DC motor is connected with the counter potential-detection device. An output of the counter-potential detection device is connected with the PWM synchronous controller and the rotating-speed calculator. The control structure of the brushless DC motor of the vehicle-mounted refrigerator is simple in structure and capable of improving work reliability of a system and reducing the fault rate on one hand and reducing the size of a controller on the other hand.
Description
Technical field
The present invention relates to a kind of control structure, relate in particular to a kind of control structure of car refrigerator brshless DC motor.
Background technology
Along with the progressively raising of people's living standard, in recent years, car refrigerator also becomes a pith of domestic and international automotive electronics accessory.Along with the development of Domestic Automotive Industry, the demand of refrigerator of vehicle is also increasing rapidly, and current automobile mounted refrigerator is divided into two kinds of electronic cooling and compressor refrigerators.Electronic refrigeration icebox is to adopt electronic cooling principle, although can not produce noise and pollution, and power supply is ad hoc vehicle power, and its refrigerator temperature generally can only remain on 10 degrees Celsius of left and right, can not truly realize the basic function of refrigerator.Compressor refrigerator has a clear superiority in refrigeration, but structure of the prior art is more complicated, and temperature is unadjustable, is all substantially to adopt simple PID to control, and controls effect not ideal enough.
Summary of the invention
The technical problem to be solved in the present invention is: structure of the prior art is more complicated, and temperature is unadjustable, is all substantially to adopt simple PID to control, and controls effect not ideal enough, and a kind of control structure of car refrigerator brshless DC motor is provided.
In order to overcome the defect existing in background technology, the technical solution adopted for the present invention to solve the technical problems is: the control structure of this car refrigerator brshless DC motor comprises speed regulator, current regulator, PWM isochronous controller, three-phase PWM inverter, current sensing means, brshless DC motor, back-emf detects and rotating speed calculator, the output of described speed regulator connects current regulator, the output of described current regulator connects PWM isochronous controller, the output of described PWM isochronous controller connects three-phase PWM inverter, described three-phase PWM inverter connects brshless DC motor, brshless DC motor connects back-emf and detects, the output that back-emf detects connects PWM isochronous controller and rotating speed calculator.
According to another embodiment of the invention, further comprise that described speed regulator connects current regulator is connected three-phase PWM inverter two junctions connection current sensing meanss with PWM isochronous controller.
The invention has the beneficial effects as follows: the control structure of this car refrigerator brshless DC motor, it is simple in structure, can improve on the one hand the functional reliability of system, reduces failure rate, on the other hand, can reduce the volume of controller.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
Embodiment
Fig. 1 is structural representation of the present invention, comprise speed regulator, current regulator, PWM isochronous controller, three-phase PWM inverter, current sensing means, brshless DC motor, back-emf detects and rotating speed calculator, the output of described speed regulator connects current regulator, the output of described current regulator connects PWM isochronous controller, the output of described PWM isochronous controller connects three-phase PWM inverter, described three-phase PWM inverter connects brshless DC motor, brshless DC motor connects back-emf and detects, the output that back-emf detects connects PWM isochronous controller and rotating speed calculator.
Speed regulator connects current regulator is connected three-phase PWM inverter two junctions connection current sensing meanss with PWM isochronous controller.
Rated speed regulates through speed regulator, and entirety is controlled and adopted two closed-loop controls.The functional reliability that can improve on the one hand system, reduces failure rate, on the other hand, can reduce the volume of controller.
