PROJECT TITLE :

Stability Analysis of Boundary and Hybrid Controllers for Indirect Energy Transfer Converters

ABSTRACT:

In boost converters and other indirect energy transfer topologies, transient-oriented controllers are designed to facilitate a dynamic response which will vary from minimum time up to minimum output voltage deviation. Since analytical definitions for these management laws will become quite advanced, a large-signal stability verification is not immediate. This paper explores the existence of stability of indirect energy transfer converters that are controlled by either boundary or hybrid controllers and introduces a brand new simplified procedure for examination of large-signal stability of a given converter and cargo type employing a graphical–analytical approach. The steadiness analysis and examination methodology are demonstrated on a boost converter loaded by resistive load and constant current load. The stability conditions are verified using a 30 W 3.three-to-12 V boost converter prototype, controlled by a programmable-deviation controller and time-optimal controller, verifying their giant-signal stability.
