| 摘 要： | 为保证敏感负载的高稳定电能供应,提出了一种应用于Z源AC/AC变流器的谐波抑制及稳压算法.通过输入电压基波量与整体量的实时比较产生的误差信号,生成占空比随时间变化的开关调制函数.通过开环方式,对变流器的输出开关占空比进行实时调节.和已有的恒定占空比控制相比,实现了对交流输入电压中低次谐波的有效抑制,并且不要求分别计算各...

| Abstract: | An algorithm of harmonic elimination and voltage stabilization is proposed for Z-source AC/AC converter to ensure its stable power supply.A switching modulation function with varying duty factor is generated based on the difference between fundamental input voltage and whole input voltage.The output switching duty factor of converter is regulated by open-loop control in real time,which suppresses the low-order harmonics of AC input voltage more effectively than the constant duty cycle control.As the harmoni... |
