摘　　要：为保证不间断电源逆变器交直流切换过程不对负载产生过大的冲击,UPS逆变输出电压必须与电网电压的频率及相位保持一致。快速可靠的软件锁相跟踪技术可以准确地为逆变器数字化控制提供与电网电压同频同相的标准正弦电压。主要讨论基于TMS320LF2407数字化控制平台的全数字不间断电源中的锁相控制技术。In order to avoid a big impact on load when the UPS inverter is switching, the output voltage of UPS inverter must be consistent with the grid voltage in frequency and phase domain. Fast and reliable software phase-locked tracking technology can accurately provide the standard sinusoidal voltage for the digital inverter with the same frequency and phase as those of the grid voltage. This paper mainly discusses the phase-locked technology of full digital UPS based on TMS320LF2407.
