Abstract

In this paper it is presented an analysis and design of a digital control algorithm implemented on a digital signal processor, a dsPIC30F2020. A dc-dc converter prototype is built based on a full-bridge (FB) dc-dc converter topology. Extensive simulations in time domain and digital domain are explored and experimental results are also shown to validate the performance of this particular dc-dc converter. Basically, the dc-dc power converter will operate in a phase-shift (PS) mode along with a current-doubler high-frequency feature. This current-doubler scheme will allow an increase of output current capability with a low dc-output voltage under special load conditions. A prototype of a current-doubler has been built and tested on a phase-shift full-bridge (PSFBC) dc-dc converter with a 6V of dc-output voltage, and 2.5A for output current. A direct digital control design methodology is discussed, as well as simulation and experimental results of a digital controller are presented. Extensive discussion on experimental results and design issues are presented.

一种简单的移相全桥DC-DC功率变换器数字控制算法的分析与设计

本文分析和设计了一种在数字信号处理器dsPIC30F2020上实现的数字控制算法。基于全桥(FB) dc-dc转换器拓扑结构，构建了dc-dc转换器原型。在时域和数字域进行了大量的仿真，并给出了实验结果来验证这种特殊的dc-dc变换器的性能。基本上，dc-dc功率转换器将在相移(PS)模式下工作，并具有电流倍频特性。这种电流倍增方案将允许在特殊负载条件下以低直流输出电压增加输出电流能力。建立了电流倍增器的原型，并在相移全桥(PSFBC) dc-dc变换器上进行了测试，其直流输出电压为6V，输出电流为2.5A。讨论了直接数字控制的设计方法，并给出了数字控制器的仿真和实验结果。对实验结果和设计问题进行了广泛的讨论。
