High-Frequency Digital Controller Applied to Voltage Regulator Modules
High-Frequency Digital Controller Applied to Voltage Regulator Modules
摘要
Digital controllers are an interesting option for the next voltage regulator module （VRM） generation due to their wide programming possibilities. This paper discloses a very interested candidate to control DC-DC power converters, the Digital Signal Controller （DSC）. For that matter, a study was done by carrying out simulations and experimental results. Moreover, an additional voltage-input feed-forward （IVFF） algorithm is given in order to show the benefits of this technology. Finally, a complete analysis of the quantization effect is presented, and its influence over the controller performance is included.
