Abstract
This paper focuses on photovoltaic systems with multiple parallel-connected panels. It is shown that distributed MPPT must be performed on each panel to maintain maximum power harvesting in partial shading conditions. This is especially true for PV systems made with panels having different electrical parameters. The multi-input, single-output (MISO) dc-dc converter provides a low-cost implementation of distributed MPPT for solar applications. A controller with digital peak and valley current control is used to operate the MISO converter in pseudo-CCM mode. A digital input current estimation algorithm based on the inductor current is proposed to iteratively reach DMPPT for each input, while eliminating the need for several current sensors in the system. The overall power benefit from the MISO converter ranges from 7% to 43% in the experimental MISO buck prototype. The proposed low-cost DMPPT solution and control algorithm provide very promising power savings compared to the conventional MPPT approach. The novel solution allows PV systems to be easily expanded without being restricted to panels from a single manufacturer.

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 it
