基于FPGA的Delta变换型UPS的研究

Study on the Delta Transform Type UPS Based on FPGA

文章在研究Delta变换型UPS拓扑结构的基础上,通过改进逆变器的控制方法,提出了一种基于FPGA(现场可编程门阵列)的UPS控制系统数字化实现方案。整个控制系统通过Altera公司的FPGA芯片EP2C5Q208C8N实现,通过Quartus II开发软件,采用硬件描述语言(VHDL)与原理图输入相结合的方法,完成了各个功能模块的设计,使得整个控制系统更加简单可靠。最后对所设计的各个模块进行了功能和时序仿真,仿真结果验证了设计的正确性和可行性。

Based on the research of Delta transform UPS, this paper proposes a UPS control system based on the FP-GA through the improvement of inverter control method. The whole control system is realized by Altera Companyg FPGA chip EP2CSQ208C8N. Combining VHDL with the schematic input method through the Quartus II, it completes the de-sign of each function module and makes the control system more simple and reliable. Finally, the designed controller is simulated in function and timing. Simulation results prove the feasibility of the proposed method.
