Design of Power Supply for Fast Repulsion Operating Mechanism of DC Vacuum Circuit Breaker
摘要
Abstract
For solving the reliable energy supply of the fast repulsion operating mechanism of vacuum circuit break-er,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 front-stage 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 fac-tor 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 con-trol of charge and discharge switches.关键词
