说明：  。本文针对三电平高压变频器控制要 求的特点，设计了基于DSP 和FPGA 的控制电路。利用DSP 进行高速浮点计算，满足实时控制的要求；FPGA 并行执行 程序，实现了多路触发信号的同时控制，而且由于采用了硬 件电路完成计算，提高了控制系统的可靠性
(. In this paper, three-level voltage inverter control requirements of the features, design and FPGA-based DSP control circuit. High-speed floating-point calculations using DSP to meet the requirements of real-time control FPGA parallel implementation of the program, realized the trigger signal, while multi-channel control, and because use of the hardware circuitry to complete the calculation and improve the reliability of the control system)
