| Abstract |
In this paper the use of a current-voltage feedback for the control of boost switching regulators is proposed. Instead of the conventional current loop with comparator used by Current Injection Control (CIC), the use of a proportional regulator in the current loop is suggested. The results of the theoretical analysis of the proposed feedback circuit based on the small signal model and computer simulation results for the large signal case are presented. The theoretical and simulation results are verified by measurements on a laboratory prototype. The advantages compared to CIC are that switching instability is eliminated and susceptibility to noise is lowered. An alqorithm is included for the design of the proposed feedback circuit. |
