Embodiment Construction

[0018] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings and preferred implementation cases.

[0019] Refer to the attached figure 1 The present invention provides a transient support protection system for a supercapacitor, comprising a supercapacitor connected to a processor, and the output end of the supercapacitor is sequentially connected to an external system through a unidirectional conduction module, a switch module, and a sampling module, The one-way conduction module, the switch module, and the sampling module are also connected to the processor. The one-way conduction module is used to control the one-way output power supply of the supercapacitor according to the voltage difference between the external system and the supercapacitor, and the switch module is used to control the external power supply. The electrical connection between the system and the supercapacitor, the sampling module is ...

Abstract

The invention belongs to the technical field of supercapacitors, and discloses a transient support protection system for supercapacitors. The system is connected, and they are also connected to the processor. The unidirectional conduction module is used to control the unidirectional output power supply of the supercapacitor according to the voltage difference between the external system and the supercapacitor. The switch module is used to control the electrical connection between the external system and the supercapacitor. , the sampling module is used to collect the changing state of the current signal from the external system, and the processor judges whether the transient support protection system is subject to high-frequency interference according to the collection result of the sampling module, and then combines the output voltage of the supercapacitor and the one-way guide The drive voltage of the pass module adopts the hysteresis control method to control the on and off of the switch module to ensure that the drive voltage of the unidirectional pass module meets the driving requirements during the period of high-frequency interference.

Description

technical field [0001] The invention belongs to the technical field of super capacitors, and in particular relates to a transient support protection system for super capacitors. Background technique [0002] As the use of supercapacitors becomes more and more popular, the application and demand for supercapacitors are also becoming more and more extensive. Because supercapacitors have very strong peak power and peak current processing capabilities, they can reach 100C charge and discharge capabilities, and can Discharge to 0V, unlike lithium batteries, does not support discharge to 0V. Therefore, in many occasions where large peak current and peak power need to be handled, the application of transient support for supercapacitors is also increasing. The state support circuit requires both performance and cost and size, and various application circuits have also been born. [0003] The traditional transient support circuit is basically unidirectional, or combined with a dedic...
