Abstract

In this paper, the low voltage stress of switches, high voltage gain DC-DC converter is proposed. The operating principle of the converter is similar to that of the conventional buck converter. Therefore, the proposed converter can be operated in the discontinuous conduction mode, continuous conduction mode, depending on the design. Moreover, the controller is also similar to that of the traditional buck converter, results in the simple controller. Furthermore, the voltage stress of every switch is reduced significantly compared with the conventional converter. Therefore, the use of the low voltage rating switches reduces the losses significantly. A 200W converter prototype is successfully built and tested to verify the feasibility of the proposed converter.
电池用新型高降压DC-DC变换器的分析与设计
本文提出了低电压应力开关、高电压增益DC-DC变换器。该变换器的工作原理与传统的降压变换器相似。因此,根据设计的不同,所提出的变换器可以在断续导通模式、连续导通模式下工作。此外,该控制器也与传统的降压变换器相似,导致控制器简单。此外,与传统变换器相比,每个开关的电压应力显著降低。因此,使用低额定电压开关可以显著降低损耗。成功地建立了一个200W的变换器原型,并对其进行了测试,以验证所提出变换器的可行性。
