摘要 针对现有"电力电子技术"教材中普遍存在的对Buck-Boost变换器的分析不完整等问题,本文基于伏秒平衡原理对Buck-Boost变换器进行了全面分析,推导出变换器全范围的输入输出电压关系,电流连续模式(CCM)和断续模式(DCM)的临界工作条件以及电路各参数对电流纹波和电压纹波的影响等。本文一方面有助于更全面深入地理解Buck-Boost变换器的工作原理及特性,另一方面有助于DC-DC变换器分析方法的统一,具有一定的教学指导意义。 There are some incomplete analyses of buck-boost converters in current materials of power electronics. Based on the principle of volt-second balance, this paper analyzes the buck-boost converter comprehensively. Next, the ratio of input and output voltage in full range is derived, and the critical working conditions in continuous conduction mode and discontinuous conduction mode are analyzed. Last, the effects of circuit parameters on current and voltage rip- ple are illustrated. On the one hand, this paper can help to understand thoroughly the operating principle of buck-boost converter, and on the other hand, it also can help to analyses DC-DC converters uniformly, which has certain signifi- cance in the teachings of power electronics.
