【摘要】 双PWM变换器是兆瓦级风力发电中的关键部件。不同的用户对双PWM变换器的控制平台有着不同的要求,为缩短开发周期、增强扩展性,建立模块化、通用型硬件和软件平台,显得尤为必要。针对此问题,设计了一套基于32位定点数字信号处理器DSP(TMS320F2812)和复杂可编程逻辑器件(CPLD)MAX7000S的全数字化控制平台。其考虑多种常用需求,建立主控制板和具有不同功能的独立子模块板,通过背板总线方式整合为统一整体,以实现模块化和通用化的目标。样机的实验结果验证了该设计的正确性和有效性。更多还原

【Abstract】 Dual-PWM power electronic converter is a key component in wind power generation.Different users have different requirements for the control platform of the dual-PWM power electronic converter.It is necessary to develop a generalpurpose hardware and software control platform.A wholly digital control platform based on 32 bit fix-point DSP(TMS320F2812) and CPLD(MAX700S) is designed,which contains a main control board and different functional boards.Experimental result shows that the scheme is valid and satisfactory.更多还原
