CPLD实现快速低开关损耗的优化SVPWM算法
- 介绍了利用ALTERA公司的Maxplus Ⅱ软件及ACEX芯片,基于一种用于三相电压型逆变器的优化SVPWM算法,来实现变频调速系统,该算法采纳Kohonen神经网络的优点。选择适当的调制方法和改进的算法,不但可以显著地缩短计算时间,且显著减少开关损耗。用复杂可编程逻辑器件(CPLD) 来实现这种算法非常简单合适。

- 恒频恒压(CVCF)逆变电源的输出电压波形质量是衡量其性能的重要指标之一。文章采用一种重复控制和双闭环控制相结合的电压波形控制策略,以重复控制器提高逆变电源输出电压的稳态精度,减小总谐波畸变率;以双闭环控制器达到较快的动态响应速度。该方案在一台采用TMS320F240 DSP控制芯片的50 Hz三相PWM逆变器上得到验证。-Constant voltage constant frequency (CVCF) Inverter output voltage waveform quality is
