采用双输入直流变换器将太阳能和风能联合构成双输入供电系统，可避免独立光伏发电系统电力供应不稳定和不连续的缺点。本文提出一种新的双输入Buck-Boost直流变换器，具备电路结构简单、电压增益高特点，联合供电系统既可同时向负载供电，又可分体单独向负载供电。分析双输入Buck-Boost直流变换器的工作原理，给出变换器的输入/输出稳态关系式，并通过PSPICE软件进行仿真。仿真结果验证了理论分析的正确性。

Instability and intermittency are two main drawbacks of independent solar energy generation. Therefore, it is essential to use a double-input DC/DC converter, which combines wind with solar to form a hybrid energy system. The paper proposes a new double-input Buck-Boost DC/DC converter with the following advantages: simple circuit, high voltage gain, and allowance of individual or simultaneous power delivery of the two sources. The operation principle of the double-input Buck-Boost DC/DC converter is analyzed, and the steady-state relation between convert input and output is presented. Finally, simulation results with PSPICE software are used to verify the theoretical analysis.
