Abstract
This paper re-examines 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 dynamic 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. The results have been confirmed by experimental measurements.
