摘　　要：本文首先提出了家庭太阳能光伏系统的组成结构,详细分析了半桥型DC/DC变换器的工作原理;分析了电压控制型脉宽调制芯片SG3525的内部结构及其控制特性,并设计了基于SG3525的系统控制电路,实现了系统的电压电流双闭环控制。最后,通过实验对本系统提出的设计方案进行了验证。The structure of domestic solar photovoltaic system is presented in this paper. The principle of half-bridge type converter is analyzed in detail. The inner structure and character of pulse width modulation chip SG3525 is elaborated too, and control circuit based on it is designed, and the double closed loops control of system is realized. Finally, the design scheme of system is verified by experiments.
