摘　　要：本文通过对二阶RLC电路求解瞬态响应的方法对半桥逆变电路的稳态工作进行了分析,求出其完整解。根据阻尼因子k的大小,得出电路几种不同工作模式下输出的电压、电流波形,它同用示波器观测到的灯的实际电压、电流波形是完全吻合的。This article analyses the steady state of half bridge invertor by means of the transient response of RLC two order circiuts under the action of a step voltage. We obtain a perfect solution of the invertor.According to the damping constant k we have three different type of output voltage and current waveform of the invertor . It is perefact proofed by the actual lamp voltage and current waveform under the examination of a oscillograph.
