摘要：逆变器输出直流分量会对逆变器本身和交流负载产生不利影响，必须消除直流分量来保障逆变器的可靠运行。提出了一种简单的消除输出直流分量的方法，并在理论分析的基础上，通过对1台220 V、1 kW的逆变器系统进行实验，验证了该方法的有效性。实验结果表明，该方案产生的基准正弦波质量高，直流分量消除效果明显。

Abstract: DC component in inverter output is an adverse factor to inverterself and AC loads, so inverter must be operated under eliminate measure. A simple method was proposed to eliminate DC component. According to theoretical analysis, an inverter system with 220 V output and 1 kW load was built in the lab verifies the validity of the method. The experiment demonstrates that the kind of reference sine wave signal has the characteristics of high quality.
Key words: inverter; direct current(DC) component; reference sine circuit
