建立了开环的BUCK电路模型，并分别以不同参数模拟了DCM和CCM模式下的buck模型。(An open loop BUCK circuit model is established, and buck models under DCM and CCM modes are simulated with different parameters.)

以matlab中的simulink搭建的boost电路。开环控制。(A boost circuit built with Simulink in MATLAB. Open loop control.)

simulink下搭建的开环cuk电路。(Open loop Cuk circuit built under Simulink.)
