摘要

本文给出了一个新的、新颖的DC/DC变换器控制概念的实现实例。它被设计用于带有DSP处理器的稳压器。控制装置使蓄积在变换器中的能量保持在稳定水平，从而间接地使输出电压达到所需值。为了验证该方法在实际设备中使用的可能性，对调节器算法进行了分析，特别注意数值复杂性和必要计算的持续时间。参考是一个定点32位DSP处理器设计用于能源电子应用。给出了处理器计算时间对变换器性能影响的补偿方法。研究和分析的结果证实了用该方法控制DC/DC变换器的可能性和吸引力。

Compensation of Calculations Duration on Converters Output Voltage in Digitally Controled Converters Based on Law of Conservation of Energy - Project "Bumblebee"

In the paper an example of implementation of new, original DC/DC converter controlling concept is presented. It is designed to be used in regulators with DSP processors. Control device keeps energy accumulated in converter at steady level, and in this way indirectly forces required value of output voltage. To check the possibility of using this method in real life devices, regulators algorithm was analyzed with particular attention set on numerical complexity and duration of necessary calculations. Reference was a fixed-point 32-bit DSP processor designed for energy-electronics applications. Way of compensating influence of processors calculations duration on behavior of converter is also presented. Results of conducted research and analysis confirm possibility and attractiveness of using the method to control DC/DC converters.
