该国产数字化电源控制器采用先进的DSP和FPGA作为控制核心,采用了高精度的ADC作为数据采集单元,并且将模拟量和数字量进行有效的隔离,设计了较为先进的PID控制算法.控制器由DSP和ADC两块控制卡组成,嵌入电源,和电源有机地融成一体.控制器通过光纤与远程IOC进行实时通讯,通过本地PC机串行口可灵活调节电源回路参数,具有高稳定性和高重复性等优点.迄今为止该控制器作为进口瑞士PSI控制卡的替换产品,主要应用在SSRF的静态的中小功率开关电源上(100ppm以下),各项指标均能满足使用要求.与进口控制器相比,该控制器有较高的性价比.
The domestic digital power controller adopts advanced DSP and FPGA as the control core, adopts high-precision ADC as the data acquisition unit, and effectively isolates the analog and digital, and designs a more advanced PID control algorithm. It consists of two control cards: DSP and ADC, embedded in the power supply and integrated with the power supply.The controller real-time communication with remote IOC through optical fiber, through the local PC serial port can flexibly adjust the power circuit parameters, with high stability And high repeatability, etc. So far the controller as a replacement for imports of Swiss PSI control card, mainly used in SSRF static small and medium power switching power supply (100ppm or less), the indicators can meet the requirements. Compared to the controller, the controller has a higher price.
