Description
Technical field
The utility model relates to the charging technique field, particularly a kind of super capacitor equalizer circuit.
Background technology
Ultracapacitor claims farad capacitor, double electric layer capacitor again, is a kind of novel energy-storing device, and it has characteristics such as charging interval weak point, long service life, good temp characteristic, energy savings and environmental protection.
Known super capacitor charger all is to adopt constant current or constant voltage mode charging; control chip is directly by the whether conducting of transducer control switch pipe; when voltage in the super capacitor is zero volt; when transducer can't operate as normal; charging control circuit lacks the circuit structure of regulating power output; thereby cause the output short circuit; make electric current enter the intermittent shorts fault; i.e. " beat every " guard mode; just can't charge to super capacitor under this state; and when voltage was lower in the electric capacity, power output did not reach the maximum power of charger design far away, thereby formed a kind of wasting of resources.In addition, there is the problem of Voltage unbalance in super capacitor in charging and use, will have influence on the useful life of super capacitor greatly.
Summary of the invention
The utility model provides a kind of super capacitor equalizer circuit at the deficiencies in the prior art, the utility model can make the charging or use in super capacitor on the balance of voltage.
The utility model is achieved through the following technical solutions:
The super capacitor equalizer circuit, comprise pressure module and control circuit at least one group, pressure module comprises flying capacitance at least two bidirectional switchs and the group in this group, in parallel with an end of a bidirectional switch accordingly on each super capacitor that is cascaded, the other end of each bidirectional switch is connected on the interior flying capacitance of group; Described control circuit is electrically connected with each bidirectional switch respectively.
Adopt such scheme, with super capacitor grouping series connection, produced periodic control signal by control circuit, make and organize each interior bidirectional switch closed and disconnected successively, every group arranges flying capacitance in the group, is responsible for the energy transmission in the group, keeps the balance of voltage in the group.
Further, described super capacitor equalizer circuit also comprises between group flying capacitance between bidirectional switch and group, pressure module is two in described group, in each group in the group of pressure module on the flying capacitance with a group between an end of bidirectional switch be electrically connected, between each group between the other end of bidirectional switch and group flying capacitance be electrically connected, bidirectional switch also was electrically connected with control circuit between each was organized.By organizing flying capacitance between the outer group that arranges, be responsible for the energy transmission between group, keep the balance of voltage between group.
Below in conjunction with accompanying drawing and the formula of specifically implementing the utility model is described further.
