空间矢量异步电机变频器-
- 我们设计的异步电机变频调速器以TMS320F28035芯片为控制核心,通过输出三相PWM波控制智能功率模块IPM驱动三相异步电机。我们使用空间矢量SVPWM算法,并对其进行了优化。采用异步电机无传感器测速算法省去了昂贵的光电编码器,大大节省了成本。同时开创性的研发了自动根据运行环境调节的自适应变频算法,使我们的变频调速器可以在电网条件恶劣的乡村山区工作,由此该变频器已被一家民用水泵生产企业预订。(We design the asynchronous motor frequency convers
光伏模拟装置
- 本系统由SPWM信号的产生、逆变回路及其控制、欠压过流保护、键盘和显示等部分组成。选择DSP TMS320F28027芯片产生SPWM信号;逆变器主回路是由功率场效应晶体管构成的全桥逆变电路,其控制部分采用基于DSP控制的最大功率跟踪和输出电流跟踪控制策略,使逆变输出电流与参考信号同频同相;并从软硬件两方面进行输入欠压、输出过流保护,增强系统的稳定性和可靠性。对系统的转换效率、畸变率等各项指标的测试结果表明,本光伏并网模拟装置是比较稳定可靠的。(The system consists of SP
