Abstract

Buck-boost converters are widely used in the development of DC-DC converters. Several techniques and algorithms have been introduced to improve the transient response of buck-boost converters. However, due to the opposite trends of the output current change and the output voltage change, undershoot or overshoot in the output voltage still seems to be inevitable. In order to overcome this problem, a novel boost-buck converter architecture is proposed to build a fast transient response DC-DC converter. The converter consists of a cascaded configuration of the boost and buck stages. The boost stage converts the input voltage to the shared capacitor voltage and the buck stage supplies energy to the load by converting the shared capacitor voltage to the output voltage. By harnessing the energy stored in the shared capacitor, the transient response of the boost buck converter can be improved to 2 Âµs in a step-up load current change of 1 A with an output-voltage ripple of 15 mV.

一种改进暂态响应和输出电压纹波的新型升压变换器结构

降压-升压变换器广泛应用于DC-DC变换器的开发中。已经引入了几种技术和算法来改善降压-升压转换器的瞬态响应。然而，由于输出电流变化和输出电压变化的相反趋势，输出电压中的下冲或过冲似乎仍然是不可避免的。为了克服这一问题，提出了一种新的升压-降压转换器结构，以构建快速瞬态响应的DC-DC转换器。该转换器由升压级和降压级的级联配置组成。升压级将输入电压转换为共享电容电压，降压级通过将共享电容电压转换为输出电压向负载提供能量。通过利用共享电容器中存储的能量，升压-降压转换器的瞬态响应可以在1A的升压负载电流变化中提高到2µs，输出电压纹波为15mV。
