| 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。 |

| Abstract: |
| 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 fixed-point 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. |
