Abstract
A direct-current feed type energy saving device for a motor belongs to the field of motor drive application and comprises a motor controller with a direct-current busbar, two independent DC/DC (Direct-Current to Direct-current) converters and a group of direct-current feed type systems formed by supercapacitors; and the direct-current feed type energy saving device is used for realizing the accurate management on electric energy under different load states of the motor so as to achieve the purpose of energy saving.
Description
Technical field
The utility model belongs to the Motor Drive application.
Background technology
Electric motor drive system is an application parts very widely; In national economy, be in indispensable status; In some particular places were used, motor worked in motor/generator and replaces transition status, and the electric energy that when motor works in the generator state, is produced is wasted.Also some electric motor drive system has adopted electric energy feedback mode at present; Promptly offer motor, also can be implemented in the function that the electric energy that is produced when motor works in the generator state feeds back to electrical network simultaneously, but this mode need adopt the synchronized inverter to carry out the energy feedback to electrical network by absorbing energy on the electrical network; Its shortcoming is when electrical network carries out feedback energy, electrical network to be produced Harmonic Interference; Influence power grid quality, control simultaneously is complicated, and cost is higher.
Summary of the invention
The purpose of the utility model provides a kind of mode of utilizing ultracapacitor energy storage, realizes the energy-conservation DC feedback formula motor energy saving devices of electric motor drive system.
The utility model comprises motor controller, a DC/DC converter, the 2nd DC/DC converter and the one group of ultracapacitor with dc bus; The ac input end of said motor controller is connected on the electrical network ac bus, and the output of said motor controller connects motor; The input of a said DC/DC converter is connected on the dc bus of said motor controller; The output of the one DC/DC converter is connected with the 2nd DC/DC converter through said ultracapacitor, and the output of said the 2nd DC/DC converter is connected on the dc bus of said motor controller.
The interchange input side of the motor controller of the utility model connects the electrical network ac bus, and its outlet side connects motor, is used for to motor electric energy being provided from the electrical network ac bus.The input of the one DC/DC converter is connected on the dc bus of motor controller; Its output is connected on one group of ultracapacitor, and its effect is that the electric energy that is produced when motor is worked in the generator state carries out energy storage by ultracapacitor after regulating.The input of the 2nd DC/DC converter is connected on the ultracapacitor; Its output is connected on the dc bus of motor controller; Its effect is when motor returns to electric motor state, the electric energy that ultracapacitor stored up to be fed back on the dc bus of motor controller, realizes the economize on electricity control of motor.
The utility model is simple and reasonable for structure, and the electric energy that when motor works in the generator state, is produced is stored in the ultracapacitor, can not produce Harmonic Interference to electrical network, ensures power grid quality, and cost is low.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model.
Embodiment
As shown in Figure 1, the ac input end with motor controller 2 of dc bus connects electrical network ac bus 1, and its output connects motor 4, is used for to motor electric energy being provided from the electrical network ac bus.
The input of the one DC/DC converter 5 is connected on the dc bus 4 of motor controller 2; Its output is connected on one group of ultracapacitor 6, and its effect is that the electric energy that is produced when motor 3 is worked in the generator state carries out energy storage by ultracapacitor 6 after regulating.
The input of the 2nd DC/DC converter is connected to the output of ultracapacitor 6; Its output is connected on the dc bus 4 of motor controller 2; Its effect is that the electric energy that when motor 3 returns to electric motor state, ultracapacitor 6 is stored up feeds back on the dc bus 4 of motor controller, realizes the economize on electricity control of motor.
