CPLD在单周控制三相高功率因数变换器中的应用

Application of CPLD in the One-cycle Control of Three-phase High-rating Factor Convertor

介绍了在三相三开关高功率因数变换器中应用复杂可编程逻辑器件 (CPLD)实现逻辑控制部分的方案。通过使用Altera公司的MAX70 0 0s系列芯片 ,以及MAXPLUSⅡ软件 ,减小了线路的信号延时 ,降低了噪声干扰 ,可以方便地随时改变控制策略 ,缩短了硬件开发周期 ,使控制电路大大简化 ,提高了系统的集成性。在替代原有的独立IC芯片控制电路之后 。

This paper introduces a scheme in which a complex programmable logic device (CPLD) is used in the three phase three pole switch high rating factor convertor to realize logic control. By using MAX7000s series chips of the Altera company and the MAXPLUSⅡ soft wares, the control circuit is greatly simplified and a very satisfying effect is achieved.
