摘要

本文提出了一种DC-DC变换器的数字控制系统,该系统可以有效地减少反馈控制系统的延迟时间。在48V/5V直接转换1MHz DC-DC变换器上进行了多次实验,评估了负载突变时的时间响应、最大功率效率和频率特性。结果表明,该系统可将数字控制器的时延降低至14.4ns,最大功率效率达到85.23%。该系统的交叉频率达到268.98kHz,相位裕度为41.20°。

48V/5V direct conversion 1MHz DC-DC converter with 14ns time-delay digital control
In this paper, a digital control system for DC-DC converter is presented, which can reduce the latency time of feed back control system effectively. Several experiments have been done in 48V/5V direct conversion 1MHz DC-DC converter to evaluate the time response to sudden load change, the maximum power efficiency and the characteristic of frequency. The results show that the proposed system can reduce the time delay of the digital controller to 14.4ns, and the maximum power efficiency is reached to 85.23%. Besides, the crossover frequency in this system is reached to 268.98kHz, and the phase margin is 41.20deg.
