Optimization and Design of a 48-to-12 V, 35 A Split-Phase Dickson Switched-Capacitor Converter
Bibliographic record
Abstract
The switched-capacitor converter (SCC) topology has been gaining attention in recent years because of their advantages of higher power density, switch utilization, and reduced component stress compared to existing converter topologies. However, SCCs have a major drawback in which capacitor charge redistribution results in significant current spikes. One method of addressing charge redistribution is split-phase operation, which accomplishes this by imposing voltage control on the SCC’s flying capacitors. However, an important design consideration was identified regarding the implementation of the split-phase Dickson SCC in high-current applications. Mismatched flying capacitors exhibit uneven charge rates, resulting in incomplete elimination of charge redistribution by split-phase control. This paper presents a discussion of the effects of mismatched flying capacitors on the operation of the split-phase Dickson SCC. Furthermore, design processes and test results of a prototype high-current split-phase Dickson SCC will be presented.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
