Motional-Current-Sensing Method and Simplified Closed-Loop Control Strategy for Piezoelectric-Resonator-based DC-DC Converters

Linbo Shao, Liyan Zhu, Zhiyang Cao

A ring-dot shaped piezoelectric transformer senses motional current to enable simplified closed-loop control and ZVS in PR-based DC-DC converters.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

It is physically proven that the proposed method is robust with various non-ideal factors of the piezoceramic and circuit implementation, and experiments verify that the approach realizes ZVS for all transitions within a switching cycle with reduced hardware and software resources.

C2weakest assumption

The ring-dot shaped piezoelectric transformer can be added without disturbing the main resonator's motional current or introducing new losses or delays that would invalidate the sensing signal; this premise enters in the description of the sensing method and its claimed robustness to non-ideals.

C3one line summary

Ring-dot PT sensing of motional current supports simplified ZVS control in piezoelectric-resonator DC-DC converters with low hardware overhead.
