摘要

为解决真空断路器快速斥力机构可靠供能问题，文中设计了市电输入条件下快速斥力机构双级充电电源软硬件系统。其中，硬件系统主电路包括前级功率因数校正（power factor correction，PFC）电路、后级半桥LLC谐振变换器以及基于LLC控制芯片NCP1399的反馈回路。基于仿真软件Cadence17.4分别对PFC电路、LLC谐振变换器进行闭环仿真分析与验证。样机软硬件系统实验结果表明，该电源系统可实现254～820 V宽电压范围连续可调直流输出，直流电流0.1～0.5 A连续可调，输出电压纹波因数为2.93%，样机满载效率可达93.7%。将所设计电源样机用于自主搭建的10 kV/15 kA直流真空断路器实验系统，能够实现充放电开关的可靠控制。

Abstract

For solving the reliable energy supply of the fast repulsion operating mechanism of vacuum circuit breaker

a two-stage charging electric supply software and hardware system is designed for the fast repulsion operating mechanism under the condition of commercial electric input. The main circuit of the hardware system includes a frontstage power factor correction(PFC)circuit

a rear-stage half-bridge LLC resonant converter

and a feedback loop based on the LLC control chip NCP1399. The closed-loop simulation analysis and verification of the PFC circuit and LLC resonant converters are performed based on the simulation software Cadence17.4. The experimental results of the software and hadrware system of the prototype show that the DC output can be continuously adjusted in a wide voltage range of 254~820 V

the DC current is continuously adjustable from 0.1~0.5 A

the output voltage ripple factor is 2.93%

and the full-load efficiency of the prototype can reach 93.7%. The designed electric supply prototype is used in the self-built 10 kV/15 kA DC vacuum circuit breaker experimental system

which can achieve reliable control of charge and discharge switches.
