摘要
首先通过分析双PWM变频器拓扑结构和现有的系统控制策略,确定了控制平台的硬件需求。采用模块化的设计方法设计了一套基于双定点数字信号处理器TMS320F2812的控制平台。同时,对各硬件单元的设计方法和所实现的功能分别进行了详细描述。该平台既可以作为双PWM变频器专用控制平台,也可以作为通用开发板使用。最后以1台55 kW的三相两电平双PWM背靠背变频器和1台2.2 kW的三相变频调速系统为例,验证了所提出的控制平台设计的正确性和可行性。
The topologies and existing control strategies of dual-PWM converter are analyzed and the hardware requirements of its control platform are determined,which is designed modularly with two fixedpoint DSPs（TMS320F2812）.The design methods of each hardware unit and its functions are described in detail.Though the control platform is designed specially for the dual-PWM converter,it can be used as a general development board.Experimental results of a 55 kW three-phase two-level dual-PWM back-to-back converter and a 2.2 kW three-phase variable-frequency speed regulation system validate the correctness and feasibility of the designed platform.
