Digital Closed Loop Control of a Three Port Series Resonant Converter for Electric Vehicles
Bibliographic record
Abstract
With the trend towards vehicle electrification, three port DC-DC converters allow an interface between the high-voltage battery pack, a 12 V battery pack and the 48 V auxiliary loads within the electric vehicle compared to conventional two-port converters. Due to the dependence of auxiliary loads on driving behaviour and passenger input, a robust controller is essential for a three-port converter to handle dynamically changing load profiles on the loading ports. This paper presents a design procedure of a digital closed loop controller (DCLC) utilizing decoupling control for a three port series resonant converter (TPSRC). The DCLC is developed on a hardware demonstrator for the voltage mode control of the loading ports (ports 2 and 3). Delays introduced from the practical implementation of the DCLC are defined to formulate inner and outer loop frequency responses and assist in compensator design. Load stability analysis is considered to determine the admissible operating region of the designed compensators. A soft start strategy to limit inrush currents in the TPSRC is utilized. Experimental results demonstrating the DCLC under voltage reference and step load changes on the hardware demonstrator of a 6 kW TPSRC are 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.
