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 (111-113) within the first power converter stage (102), intermediate power delivered to a subsequent or second power converter stage (104) can be varied so that the multi-stage power conversion system (100) may respond to a full load step while offering improved light load power conversion efficiency. A power estimation circuit (122) within the second power converter stage (104) can provide a control signal (C1-CN) to each of the controllable networks (111-113); the controllable networks (111-113), in turn, can provide network signals (SI, S2) to control the intermediate power delivered to the second power converter stage (104).
