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220V、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。　DC component in inverter output is an adverse factor to inverter-self 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.
