Design of Intelligent Fast Switch Controller Based on CPLD
School of Electrical Engineering, Beijing Jiaotong University, Beijing 100044, China
In view of the large volume, complex structure and many transmission links of the current circuit breaker operating mechanism, a new type of electromagnetic actuator and electronic controller are used to shorten the operation time. This paper introduces the hardware and software design of an intelligent fast switching controller based on CPLD. The hardware circuit design of the controller is mainly described, including power supply conversion and charging voltage monitoring, switch state monitoring, control command monitoring, relay output, LED indicator and split switch driving module. The optocoupler isolation is realized between input and output, and the thyristor module is used to drive the capacitor discharge. The feasibility of the design circuit is verified by the actual sampling waveform, which has the advantages of high-speed operation, intelligent control, high technical performance and reliable operation.
