摘要

针对用电系统中关键负载在双电源间的切换过程，提出了一种带有电网电压定向的三相逆变电源，该逆变电源通过跟踪电网电压来实现关键负载在电源切换时无冲击。本文设计了硬件过零检测电路完成电网电压定向，搭建了基于DSP2812芯片的逆变电源实验平台并编写软件程序，实验结果表明了该逆变电源的可行性。%Based on the process of switching between the dual power for Critical loads in the electricity system. A three-phase inverter power supply system with a grid voltage oriented was proposed, The inverter power can achieve the critical load without impacted by track the grid voltage when the power switching, A hardware of zero-crossing detection circuit was designed to achieve the orientation of the grid voltage. A inverter power experimental platform was built by taking TMS320LF2812 chip and software program was write. The experimental results indicated that the inverter power is correct and feasible.
