摘要
便携式电子设备一般采用锂电池供电,随着低电压装置使用量的增加及其多功能化的增强,有效的电能管理技术成为这类设备延长电池寿命的有效方法.鉴于此,本文提出了一种buck-boost变换器的拓扑电路及其控制方法.对这种变换器所做的仿真结果表明,新的控制方法能缩短过渡时间,减小过渡时的超调,有效延长了锂电池的使用寿命.
Li-ion battery is the common choice for most portable applications. With the increasing use of low-voltage portable devices and increasing requirements of functionalities embedded into such devices, efficient power management techniques are needed for longer battery life. A topology circuit of buck-boost converter and the control for this converter are proposed in this paper. The simulation results show that the proposed control method for this converter can minimize the transient process, reduce the overshoot, and effectively lengthen the battery life.
