摘　　要：文中将耦合电感应用于断续Buck变换器,分析了耦合系数对电流纹波和动态性能的影响,给出了参数设计方法,并进行了仿真实验研究。结果表明,通过合理的设计,耦合电感能够改善电路的稳态和动态性能,同时降低了损耗,提高了电路的效率。Applying the reverse coupling inductor to the interleaving parallel Buck converter, the influences of the cou- pling coefficients of inductor on the current ripple and the dynamic response of the interleaving parallel Buck converter is an- alyzed. In this paper, the design method for reverse coupling inductor is described, and the simulation and experiment re- sults demonstrated that reverse coupling inductor can improve steady-state and dynamic performances of the circuit with the proper design, at the same time, reducing losses and improving the efficiency of the circuit.
