Abstract :
An improved current-injected modelling method is used to obtain in an easy but accurate way the transfer functions of a DC-DC converter controlled by output equalization. The approach has been used to develop an output voltage regulator with a near-optimum behavior that does not need much hardware. The principle is very general and could be used in other applications. The problem of open-loop instability and the effect of the input filter and its stability are investigated. Experimental results for the output voltage regulator are presented.
