Embodiment Construction

[0027] The present invention is a charging device for a supercapacitor bank based on current feeding topology, voltage mode control and feedforward compensation control designed for supercapacitor charging or detection. Such as figure 1 , figure 2 As shown, the supercapacitor charging device is mainly composed of electrically connected single-phase input rectification unit 1, input control switch unit 2, input switch drive unit 3, current feeding topology unit 4, EMI processing unit 5, signal acquisition unit 6, The drive unit 7, the output switch control unit 8, the output switch drive unit 9 and the control and protection unit 10 are composed.

[0028] Single-phase input rectification unit 1 converts single-phase AC power into DC power with less pulsation; single-phase AC voltage input passes through single-phase full-bridge uncontrollable rectification circuit to obtain pulsating DC voltage;

[0029] The input control switch unit 2 conducts self-inspection on the system,...

Abstract

The invention relates to a super capacitor charging device. The super capacitor charging device comprises an input control switch unit, an EMI processing unit, a signal collection unit, a driving unit, a control and protection unit, a single-phase input rectification unit, a current feed topology unit and an output switch control unit which are electrically connected. The device charges a super capacitor by adopting a current feed topology structure and voltage mode control and feed-forward compensation control technologies, and can realize a mode of two-section charging for the super capacitor, thereby realizing wide input, high efficiency, low cost, reliable performance and strong applicability of the charging device, and greatly promoting the process of industrialization of the super capacitor. The device provided by the invention is applied to charging of super capacitor banks with wide AC voltage input.

Description

technical field [0001] The invention is a device for charging a supercapacitor. The supercapacitor bank can be charged by the device, and a two-stage charging mode for the supercapacitor can be realized. The device is suitable for charging supercapacitor banks with wide AC voltage input. Background technique [0002] The power source of a pure electric vehicle is a battery. Affected by the characteristics of the battery itself, the battery has a weak ability to withstand shocks. As a kind of electric double layer capacitor, a supercapacitor has high power density and efficiency due to special raw materials and manufacturing methods. , has the dual characteristics of battery and capacitor, and becomes a power source with excellent performance. Supercapacitors meet the market's demand for high-frequency, high-intensity, high-cycle power sources that comply with environmental protection policies, and have excellent development prospects in the fields of electric vehicles, elec...
