摘要
介绍了便携式太阳能发电系统的组成,直流变换模块和逆变模块中主电路和控制电路的设计,给出了电路中各主要器件的具体参数,并给出实验结果。直流变换主电路采用带高频变压器的推挽电路、全桥整流和滤波电路。控制电路采用专用的脉宽调制集成电路芯片;逆变电路采用全桥逆变电路和滤波电路。控制电路采用AVR单片机,产生单极性正弦脉宽调制(SPWM)的控制信号,使主电路输出标准的正弦波交流电压。
A construction of a portable PV generation system was introduced,along with which were the main circuit topology and the design of control system.Parameters of the key components were designed,and the experimental results were showed.The DC-DC converter employed a push-pull topology with high-frequency transformer,full-bridge rectification circuit and filter circuit,while a specified PWM IC was adopted in the control system.The main circuit of DC-AC inverter consisted of a full-bridge circuit and a LC filter,while an AVR SCM took the role of controlling and producing a unipolar SPWM signal,which enabled the DC-AC inverter output a standard sinusoidal voltage.
