[LEVY78A] Levy, A. Investigation of the Power Supply's Turn-On and Turn-Off Dynamics, IEEE Power Electronics Specialists Conference - 1978 Record, pp. 317-324.
The dynamics of circuit interaction in terms of inrush current, stress level on components and the viability of protection and monitoring networks during the turn-on and turn-off intervals is investigated. Of special interest is the buildup and release of energy stored within the unit. Several methods for proper sequencing during the above transitions are outlined with particular focus on the behavior of pulse-width modulated units.

An analysis technique is presented which permits the designer to explore the start-up transient of a dc-to-dc converter when it is powered by a current-limited source. The current versus voltage characteristics of the source are superimposed upon those of the dc-to-dc converter. By noting the nature of the intersection of these curves in the voltage-current plane, we are able to predict whether or not the converter is able to start up while powering a specified load.

Analytical and experimental considerations on the large-signal transient-responses of the buck-type switching regulator are described. The behavior under the large-signal operation is different from the case of small signal because of the saturation characteristics of the PWM feedback controller. The effect of this non-linearity is analyzed by dividing its operation into three modes. As a result, the maximum peak values of the inrush current and output voltage are obtained analytically both for the start-up and for the step change of the load current.

This paper introduces an adaptive start-up control law for dc-to-dc converters powered from a current-limited source. This control law permits the static turn-on characteristics of the adaptive control law ensures a successful system start up over a wide range of source and load conditions. In addition, the output voltage is guaranteed to increase monotonically with time. These performance features are particularly useful in distributed powering systems, because they permit a single design to serve the needs of many different applications. The expressions derived in this paper to predict the static and dynamic start-up performance of a dc-to-dc converter are shown to be in good agreement with experimental measurements. Finally, a comparison of this control law to other popular start-up techniques demonstrates the usefulness of its adaptive features. (AUTHOR ABSTRACT) Special discussion: Reviews the problem of latchup into an undesired operating mode when dc-dc converters are powered from current-limited sources. Discusses the short comings of various solutions. Proposes an adaptive technique to overcome the shortcomings of prior approaches.
