摘要
Buck型直流变换电路在直流传动、蓄电充电和开关电源等电力电子变换装置中得到了广泛应用。带LC滤波的Buck型直流变换电路在电路结构、输入输出等效电路及波形方面存在着很强的对偶性。文章结合带LC滤波的Buck电路模型,通过对电路做等效变换、理论解析和波形分析,研究了电路中存在的对偶性。并建立了MATLAB/Simulink仿真模型,仿真分析的结果验证了有关理论和对偶性分析方法的正确性。
Buck circuits have been widely used in DC drive, charging and storage circuits, switching power supply and other power electronic devices. The Buck circuit with Input LC Filter has strong duality in circuit structure, input- outpupt equivalent circuit and waveforms. Through theoretical explanation, waveform analysis and equivalent transfor- mation of the circuit, the duality existed in the circuit is studied based on Buck circuit model with input LC filter. With proper parameters chosen, the model is simulated by MATLAB/SIMULINK, and simulation results verify theo- retical and duality analysis.
