| 摘 要： | 本文采用数字信号处理器实现了对大功率高频开关电镀电源的数字化控制,并对主电路系统设计和移相全桥变换器的PWM数字控制进行研究.电源采用模块化结构设计,模块之间通过CAN总线实现相互之间的通信和控制,构成N 1冗余结构,使电源系统具有很强的灵活型和可靠性.3台12V/1000A高频开关电源的并联实验结果表明,本文所研制的电镀电源具有良好的控制效果.

| Abstract: | In this paper,the digital control of high-power high-frequency switching electroplates power supply is realized with DSP(Digital Signal Processor) TMS320LF2407A,and the system design of main circuit and PWM digital control technique of phase-shift full-bridge converter are investigated.The supply is designed with module structure,and different module communicates with each other through CAN(Controller Area Network) bus.This design style makes it easy to realize N+1 redundancy structure,and enhance flexibility and reliability of supply system.To validate the effectiveness of the proposed control methods in this paper,three-12V/1000A shunt-connection high-frequency switching electroplate power supplies are built and experimental results show that the supply is of good control performance. |
