Analysis and experimental study of an output feedback controller for a high-order boost dc-dc converter

The analysis and experimental investigation of an analogue output feedback controller for high-order boost dc-dc converter is presented. The controller incorporates both damping and integral action for enhanced performance. A comparative study of the conventional PI controller and the proposed controller shows that the latter´s suitability for the highorder converter has a sound theoretical basis. Some experimental results are provided to illustrate the features of the controller in the presence of reference voltage and load changes.
