Abstract
The paper presents the instability mitigation of three-phase full bridge diode rectifier feeding buck-boost converter using loop cancellation technique. This technique is used to overcome the instability operation. The mathematical model of the proposed system derived from the DQ method and the generalized state-space averaging method (GSSA) is used with the eigenvalue theorem for stability studies. The intensive time-domain simulation of MATLAB is validate the stable point predicted from the theory. The stabilization results show that the unstable system due to a constant power load can become back to stable system by using the proposed technique.
