Abstract

This paper reexamines the conventional current-mode control strategy as applied to dc/dc converters in the light of `avoiding bifurcation'. This alternative viewpoint permits convenient selection of parameter values to guarantee stable operation. Slope compensation is viewed as a means to keep the system sufficiently remote from the first bifurcation point. It is shown that excessive bifurcation clearance is accompanied by undesirably slow dynamical response. A variable ramp compensation is proposed to dynamically adjust the slope magnitude such that the system is kept clear of bifurcation yet responding sufficiently fast during transients.
