Design and Performance of a Resonant LLC 48V Voltage Regulator Module with a Self-sustained Oscillation Controller
Bibliographic record
Abstract
This paper presents the performance and design of a new 48V/1.5V Voltage Regulator Module (VRM) for the stand-alone high-end servers, and notebook computer applications. The proposed VRM is based on the LLC-type resonant converter as it possesses much lower component stresses compared with the conventional series and series-parallel resonant topologies. Self-sustained oscillation control (SSOC) operation is used to achieve voltage regulation and high efficiency for a wide range of load currents. It is a new current mode controller for resonant converter, hence offers lower power component ratings than with the conventional variable frequency (VF) controller and a very fast transient response. It allows a minimum power factor angle and consequently a smaller primary current to reduce conduction losses, leading to a better working efficiency. Analytical, simulation and experimental results of a 48V/1.5V 30W prototype are presented to offer the proof of concept.

How this classification was reachedexpand
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.
