Hi,
As it was discussed in Friday session, the filter design is done after control loop design. Then it is suggested to minimize the effect of the filter design in the overall design using the proposed theory.
I was wondering why the filter design is not performed before control loop design. This would provide the chance to design the control loop in such a way to compensate for both filter and converter working together. What is the disadvantage of that approach?

ReplyDeleteI think the converter Gvd becomes too complicated and difficult for a control loop design if the input filter is designed first and included with the converter.
Also, from a practical standpoint, designing the converter and control loop alone can be difficult because of cap ESR, temperature range requirements, etc.. I think designing the input filter after the converter and control loop is a more manageable process.
