A low power electronics converter with input resistance control for piezoelectric energy harvesting
Bibliographic record
Abstract
This work describes the modeling and analysis of a low power electronics converter for piezoelectric energy harvesting. The proposed converter consists of a diode bridge rectifier, a MOSFET switch driven by a PWM signal, and a rechargeable battery as the storage device. The circuit is used to convert mechanical vibration energy into electric charge stored in a battery using piezoelectric transducers mounted on a flexible structure. By utilizing an averaging scheme, it is shown that the converter exhibits a pseudo-resistive behavior across its input terminals. An analytical expression for the input resistance of the converter is derived and further evaluated by simulations and experiments. A self-powered converter is utilized to convert vibration energy into electric charge whose input resistance can be set to a prescribed value depending on the input source resistance. It is also shown that by applying a feedback controller to the circuit, the input resistance of the converter can be regulated to a desired value. This feature may be utilized to achieve impedance matching in applications requiring maximum power transfer. Experimental studies are conducted to verify the performance of the self-powered circuit and the feedback control scheme.

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.
