一种多开关结构的固态功控系统的开发

本文介绍了一种利用复杂可编程逻辑器件(CPLD)设计28V 直流固态功控系统的方法,
对整个系统进行了详细的介绍和说明。固态功控系统由控制和逻辑部件、固态开关部件和电流感受部件组成。固态开关部件采用电力MOSFET 做软开关,使得电路通断时,不会出现打火花的现象。在可编程逻辑区,运用硬件描述语言(VHDL)在CPLD 上实现了SSPC 的控制和逻辑功能。

Abstract: This paper introduces a design of the 28V DC-SSPC using complex programmable
logic device (CPLD).A detailed description of the whole system is presented. The SSPC is
composed of control and logic device, solid-state switch device and current-sense device. The olid state switch device uses power MOSFET as soft switch, so, the spark doesn't appear when he circuit turn on or turn off In the design of programmable logic units, the logic control function f SSPC is accomplished by Very-high-peed-IC Hardware Description Language (VHDL) rogrammed on CPLD.
