基于 DSP／FPGA 的级联型固态变压器控制研究
Research on cascaded solid state transformer control based on DSP/FPGA
摘要
Abstract
Cascaded solid state transformer ( Cascaded SST ) is the core equipment on building energy internet .There is a problem that single processor cannot control faster or provide enough PWM signal ports for cascaded SST .This pa-per introduces a cooperative control processor based on DSP and FPGA , after analyzing the principle of cascaded SST . Within the cooperative control processor , main algorithms are performed by the DSP , and duty cycle data is sent through SPI bus .PWM modulation is performed by the FPGA based on carrier phase shift technology that achieves higher performances by the parallel architecture .At the same time , the GPIOs in the FPGA meet the number require-ments of PWM ports.The experiment is carried on a prototype of 380 V/2 kW two-level cascaded SST , and the exper-imental results demonstrate that just one cooperative control processor can increase the number of PWM ports and suit the cascade module automatically , and control whole cascaded SST system , which is feasible and effective .关键词
