一种小功率UPS逆变器的设计与仿真

Design and Simulation of a Low Power UPS Inverter

UPS采用静态在线式系统,逆变器主电路选择单相半桥电路结构,根据工作原理以及调制方式进行逆变器电路设计,之后在Matlab/Simulink中对所设计的逆变器进行建模仿真,仿真结果表明小功率UPS逆变器的设计是合理、可行的。

The static online system is used in UPS,single- phase half bridge circuit is chosen for the main circuit of the inverter. The inverter circuit is designed according to the work principle and modulation way,then modeling and simulation of the inverter designed is made in Matlab / Simulink. The simulation results show that the design of a low power UPS inverter is reasonable and feasible.
