摘要

Abstract

The bi-directional DC-DC converter (DDC) is commonly employed for a battery or supercapacitor (BA/SC) to accomplish power management flexibility. Current and voltage control for the DDC is crucial for power management. Focusing on control of the DDC

this paper first proposes a simple order-reduction control method for the first-order system

then applies the proposed control method to current and voltage control of the SC DDC. The effect of the inner current loop on the outer DC bus voltage loop is also analyzed. With the proposed simple order-reduction control method

the dynamic response of the SC DDC is obviously improved

and robustness to the SC voltage variation is achieved. The double-line-frequency ripple is also eliminated through the proposed simple and effective method. Finally

the effectiveness of the developed control algorithm is tested by the experiment.
