一种具有占空比和控制电流预测器的单电感多输出Buck/Boost DC-DC变换器

A single-inductor multiple-output (SIMO) buck/boost dc-dc converter with average-current control is presented in this article. With the proposed duty-cycle and control-current predictor, fast and robust reference tracking of inductor current is achieved. The conventional charge-balance method is modified together with an auto-tuning-divider-based duty generator to release the cross-regulation to t...
