详细论述了断续交错双BOOST DC/DC变换器在光伏发电系统最大功率跟踪的应用。用交错BOOST电路结构能够对太阳能板萃取最多的功率和减小输出纹波，并用滑模变控制(SMC)自适应跟踪不确定光伏发电系统的最大功率点，快速达到最大功率点切面上滑动，从而使负载获得最大功率及整个控制系统在输入、输出参数扰动的情况下实现强鲁棒控制(ROBUST control)。同时通过仿真和实验验证滑模技术能在光伏交错双BOOST变换器中减小负载的纹波电流，提高光伏效率。

Study on Maximum Power Point Tacking in the Photovoltaic Generation System

The application of un-continue double BOOST DC/DC inverter maximum power point tracking control of the photovoltaic generate system is discussed in detail in this paper. Interleave BOOST circuit is capable of absorbing and reduce the output wave. Then sliding model control technology used in the system can track the max power of the uncertainly photovoltaic generate system adaptively and real-time go into sliding surface，consequently obtain the maximum power. The whole system is able to improve the performance of robust control in the case of input/output parameter perturbation. The simulation and the experiments show that the sliding-model control technology is capable of reducing the ripples current of the load of in the double BOOST DC/DC interleave convener and improving the efficiency.
