Abstract
Apparatus and methods for controllable networks to vary inter-stage power transfer in a multi-stage power conversion system are disclosed herein. By using controllable networks (-) within the first power converter stage (), intermediate power delivered to a subsequent or second power converter stage () can be varied so that the multi-stage power conversion system () may respond to a full load step while offering improved light load power conversion efficiency. A power estimation circuit () within the second power converter stage () can provide a control signal (C-CN) to each of the controllable networks (-); the controllable networks (-), in turn, can provide network signals (SI, S) to control the intermediate power delivered to the second power converter stage ().
