| 摘 要： | 采用双输入反激DC/DC变换器实现了太阳能电池和市电两种能源对负载的稳定供电,根据各种太阳能电池的特点,提出了双输入反激DC/DC变换器的控制策略:一方面使太阳能电池工作在最优状态,实现输出最大功率点跟踪,提高太阳能的利用率;另一方面当负载变化以及太阳能电池输出能量不足时可以从市电获取足够的能量以保证输出电压的稳定.最后通过仿真与实验,验证了本方案的可行性.

| Abstract: | Two-input flyback DC/DC converter is used to steadily power the load with photovoltaic(PV)array and commercial AC lines.The control strategy is proposed based on PV array characteristics.The conrerter can improve the utilizing efficiency of the PV array under the best state to supply the maximum power and keep the output voltage constant by obtaining enough energy from the commercial AC lines when the load changes or PV array cannot provide sufficient energy.Simulation and experimental results verify the feasibility of the proposed converter. |
