摘要

在混合能源系统中，由于直流母线电压波动较大，开关电源变换器对直流负载的稳定性要求较高。本文的目的是研究数字峰值电流控制dc-dc变换器在输入电压波动情况下的稳定性特性。在输入电压波动的情况下，该方法比数字电压模式控制方法具有更高的稳定性。结果，相位裕度提高了四倍。

Stability characteristics of digital peak current control DC-DC converter under input voltage fluctuation

Switching power converters connected to dc loads need high stability because the dc bus voltage is fluctuated in the hybrid energy system. The aim of this paper is to present stability characteristics of a digital peak current control dc-dc converter regarding input voltage fluctuation. The proposed method shows higher stability than the digital voltage mode control method even though the input voltage is fluctuated. As a result, the phase margin is improved by up to four times.
