| 摘 要： | 文中介绍了一种应用于UPS的新型双Boost电路拓扑，可以实现DC／AC单级升压变换。在对主电路拓扑和工作原理进行分析的基础上，采用SPWM调制方法对其进行了软件仿真和硬件实验。实验结果证明，以Boost变换电路可以实现高频功率变换情况下的单级升压逆变输出。

| Abstract: | A new dual-boost circuit topology used in UPS, which can realize the single stage DC/AC converting, is introduced in this paper. On the analysis of working principles and topology structure of the main circuit, we simulate and test the circuit under SPWM. The results show that the dual-boost inverter could generate larger AC voltage than the DC input voltage. |
