| Abstract_FL | Auxiliary inverter is used to power supply electric locomotive auxiliary devices and its operation performance affects the operation of electric locomotive directly. A new system structure based on DSP and FPGA was adopted to the auxiliary inverter core control system. A simplified three-level space vector pulse width modulation( SVPWM) algorithm which can relieve digital signal processor ( DSP/MCU) from heavy computation task through the simplified design of multiplier and divider units was adopted to the auxiliary inverter core control system. In order to make full use of high-speed parallel processing ability of FPGA, implementation scheme of AD capture and data processing, asynchronous communication between DSP and FPGA based on dual-port RAM were proposed in this paper. Finally, accuracy and feasibility of FPGA part in the auxiliary inverter core control system were verified by hardware-in-loop experimental platform based on RT-LAB and the auxiliary inverter core control system. |
