Abstract :
A single-switch dual-output buck DC/DC converter with digital time-multiplexing control (TMC) technique is presented in this paper. Adaptive weighted voltage control (WVC) is introduced over the existing fixed WVC for power conversion and it is capable of flexibly and dynamically distributing output voltage errors. The digital TMC is implemented by a low cost micro-controller. Simulation and experimental results are reported to show the effectiveness of the proposed approach.
