摘要

逆变器可将直流电能变换为交流电能，可用于构成各种交流电源，在实际中得到广泛应用．现代工业的发展对逆变器的电压等级、设备容量和谐波含量等指标提出了更高的要求．分析了电压型逆变器主电路结构优化措施，并在MAT—LAB／Simulink中进行了仿真分析．仿真结果表明所采用的优化策略可使逆变器输出获得更高的电能质量、更低的谐波含量．%Inverter can transform DC power to AC power and it can be used to create various AC power and widely used in practice. The development of modem industry put forward higher requirements on inverter such as voltage levels, equipment capacity and harmonic content and the other indicators. This paper analyzes the main circuit of optimization measures voltage inverter, and simulation is carried out in the MATLAB/Simulink. Simulation results show that optimization strategy can achieve higher inverter output power quality and lower harmonic content.
